Raw Transcript

This is a ti 89 Titanium program app. uh… regarding Implicit Differentiation. Let’s get started here

to enter my menu in my programs you have to press second alpha and then put the letters

i n d e x and then press alpha again enter the eight and the open and closed parentheses press enter and you’re into my menu many things on here, eliminating the parameter, e to the x integrals

anything you want for passing calculus and and uh… your homework we want, implicit differentiation and we’re going to enter our function. Press alpha, you have to press alpha before you enter anything in my menus or my entry lines alpha x cubed plus x squared times y cubed

minus three times y squared equals one. I show you what you’ve entered you can check your

entry here and see if it’s ok. I say it’s okay. And you notice within implicit differentiation your your taking the derivative of every term in that function on both sides and so we start take the first term take the derivative we take the second term but here’s a times sign between it, so we need to do the product rule on it and i show you how to do that here’s the formula, you write all this down on your paper f of x equals x squared, f prime of x equals two x g of x equals y cubed, g prime of x equals three y squared dy dx and here’s your answer if your professor doesn’t do that product rule and just comes up with this, then just put the answer down and then we continue with our derivatives of each term in that function and there’s the next one here’s the one on the equal sign, ya know, for the one and so differentiating both sides of the function. We get you write all this down

and here’s your answer now you can evaluate it at a point for instance you have to press alpha again. Let’s say press alpha four and alpha two show you again in case you made a mistake and then you write this notice you’re entering all the variables into your function and it shows you the slope of the line actually shows you also the the way the vector is pointing which is three hundred twenty eight degrees.

Hey this is tom the calculus and physics guy who programs the TI89 calculators and other calculators for the TI system. uh…today or this video I’m going to be talking about or showing you how fabulous my programs work on vectors my site is EveryStepCalculus.com and enjoy my program.

This is two vectors in space uh… starting from the origin to x_y_z_ uh… points you notice we start again from the index8() and in the home screen to get to my programs and up comes a menu with all these different types of things that you can compute and we want to do the vectors today so we’re gonna do a-b and vectors.

We add the first one is it asking for thex_y_z_ point of the first vector uh… vector a again and x_y_z_ and alpha 8 alpha minus seven, alpha minus three, vector b alpha six, alpha minus five, alpha seven shows us what we have if that’s correct and you can go here and press ok.

Now you notice they have the magnitude of vector a choose that one and you can see where the magnitude comes to eleven units uh… shows you how to do it eight squared you know square root of 8 squared minus seven squared minus three squared.

Go back vector B same thing press the this shows you how to do that part uh… a minus b all these different vector calculations come up I wanted to do them when I was in college quickly and not waste time with it and get them exactly accurate.

Vector a minus b is 2 minus b minus 10 if you want to find the magnitude of a minus b you can go a minus b and find that the shows you how to do exactly that putting in the variables dot product and then we’ll move on here got all these different choices.

A cross product…length B times a cross product B times A there’s a difference uh… constants against a times b times a area of a parallelogram component of A in direction of B equation of a plane all these things cross product is pretty cool ’cause that’s a matrix system and shows you there and then does all the calculations for you and there’s the in the cartesian system i j k system or the vector system with the arrows on the ends of it.

Chain Rule Examples | Video | TI89 | EveryStepCalculus

October 30, 2012 by Tommy Leave a Comment

Chain Rule Video Transcript

This Video is on Chain Rule Examples, the chain rule, and chain rule calculus

If you see in a given problem, a function under a radical sign, or a function enclosed

in parenthesis where that function is taken to a higher power in other words has an exponent,

or a trig function such as sin, cosine, or tangent where there is something more than

an x in the parenthesis of that trig function, you are using the chain rule.

To get to my menu You have to press second alpha on the Titanium

to enter letters in the home screen, and then you enter the letters i n d e x

press alpha again and enter the eight and the closed parenthesis

Press ENTER and you’re into my menu

You choose “chain rule” by scrolling down to it, or pressing the number before it, in

this case the number five

You are given four things to choose from here One, a function under a radical sign

Two, Anything enclosed in parenthesis to a power

Three, If you are already given “y” and “u”

And Four, the trig functions with something more than an x involved

I’m demonstrating the first option in this video, the function under a radical sign

So press one and you’re into the program

Enter your radical function

Now, If you enter a radical function like I’m doing here, you will be told that you

must change the radical to an exponent function and bring you back to the entry line to do

it. Generally you must always do this in calculus for radicals

So change the function:

for a square root sign, the exponent is a one half , for a cube root sign it would be

one third

I show you what you’ve entered You can change it if you want

I say it’s ok

You write all of this down on your paper or homework

Here’s the formula Here’s the choice for u

And u prime

You back substitute for u

And here’s your answer

Recent Testimonials Summer 2013:

Tom- I showed my ex, who is a calculus professor, and he was waaaaaaay impressed. And he is an arrogant ass, who never helped me ever…I could tell he wanted to hate on it, but he couldnt.

Kristin P

Tom…I think that I’m finally done with Calculus II. In the prior test I got 78 and yesterday I finished all the problem on the test. I think I should be able to remain around the same grade. Thank you so much for your help; your programs really made the difference. They didn’t just solve the problems for you, in my case, they gave me the confidence and security I had lost with those stupid professors and the way they teach. To be honest, studying the programs on my calculator taught me how to solve problems that I couldn’t do before due to the way they were presented. I felt confident and secure yesterday, and it only possible because either I remember how to do the problems or the calculator would. Thanks one more time for time, dedication and quick responses. There is no other person in the whole world that would do what you do for us , college students being killed with freaking calculus classes. John

Tom- Got it to work with that link you sent me! Just wanted to say thanks for all the great work you do, and for helping me pass this calculus class. I’m going to tell everyone about this and make them pay the $30 dollars because you have done a splendid job programming my friend. Let me know if you have any new programs for derivatives or integrals and Ill let you know if I need any more help! Much thanks, –Eric

I basically just needed to say that you’re an amazing man. Basically saved my life during my emag theory course

-DoubtingThomas (Youtube vectors review here)

oh my god I figured it out. You’re the freaking best! -Sarah

Thanks Tom. I appreciate you taking the time to break down and explain these to me. :0) –Nelson

Tommy, Great talking with you last night. I already liked you for developing this “most excellent program” but after our conversation I concluded you to be a great guy. I’ve been playing with this program most of the night, took in a few “z’s” and am back for more. This program really is superb. I did, however, notice that for some unknown reason when I attempt to do Relative Extrema’s and Trajectories that both programs came up as “Program not Found”. I’m not sure if I will be encountering the Trajectory stuff in this semester of Calculus but I do have a test this Thursday that includes Relative Extrema. Any suggestion, oh Master of this great creation?! I’m going to be gone most the day but should be home late afternoon if you got time to call. Same number (843-xxx-xxxx). That’s Myrtle Beach, 3 hours ahead of you and more golf courses than you can shake a stick at. Thanks -Joe

Wow! Awesome! These are great, so great, thank you! -Kristen

Tom is the man! His program is helping me pass my calculus class. He was willing to help me immediately when I couldn’t get one of the programs working! This application is in my opinion a STEAL! I’ve never met Tom in person but I’ll owe passing this class to every step calculus.

Calculus Cheat Sheet Video Transcript

Ok, today I’m doing a calculus cheat sheet video, many of you have asked about that,

and I’m going to do one for you here on my programs. There is no better cheat sheet

for calculus than my programs in your Titanium calculator, you load them in there. All you

want from a cheat sheet is a formula, and how to do the problem, step by step, to solve

the problem, so that you can either memorize it or learn it or help you. You’re not interested

in learning it, not interested in memorizing it, I understand. Even better in my programs,

you can add your own variables in my programs, where you can’t on a cheat sheet, so therefore

you get the actual calculations and the actual answer. A cheat sheet gives you formulas and

that’s the first thing that my programs do. When you run my programs, I give you the

formula and you write that down on your paper, the first thing to get started. And then you

go from there. So let me show you about my menu a little bit here. To get to my menu

you have to press index, put in this formula here, index eight closed parenthesis, you

do that by pressing second alpha on your calculator, and putting in these letters, I n d e x, and

then pressing alpha again and put in the eight and the closed parenthesis, and then you press

enter and then you’re into my programs. You have vectors, notice a and b vectors,

and you have x,y, and z vectors but if you only have two vectors you can put zero in

for the z variable. And you scroll down look at acceleration, arc length, chain rule, concavity,

I do graphing by hand in my programs, critical points, there’s more graphing by hand, cross

product is a vector calculation, curl for calculus three, definite integral, definition

of a derivative which is really difference quotient here. That’s the first week of

calculus very very difficult and very, very useless, dot product, all kinds of things

here, e to the x integrating, exponential functions, and uhm, implicit differentiation

that’s always good. Ah also all the way down for many, many different things, even

has something for money in here if you want to find the time value of money equations

for calculus, of course we have the quadratic equation, where you can just get the answer

by putting in your variables in your equation or I do it step by step, if you want that,

quotient rule, speed, calculations for a sphere, mid point, sphere equations, volumes for a

sphere, radius, and of course trig and half angle formulas, which are very important because

the calculators cannot enter secant or cosecant and you need to convert those to sign or cosign

to be able to do that and of course I give you the integrals and derivatives of those

trig functions, there’s no step by step its just memorization. So check out my web

site. www.EveryStepCalculus.com and now also www.EveryStepPhysics.com

don’t forget my physics programs, ah and have a good one.

Chain Rule, If you see in a given problem, a function with a square root sign, or a function enclosed in parenthesis where that function is taken to a higher power in other words has an exponent, or a trig function such as sin, cosine, or tangent where there is something more than an x in the parenthesis of that trig function, you are using the chain rule. To get to my menu, you have to press second alpha on the Titanium to enter letters in the home screen, and then you enter the letters
ex press alpha again and enter the eight and the closed parenthesis. Press ENTER and you’re into my menu. You choose “chain rule” by scrolling down to it, or pressing the number before it, in this case the number six. Then press ENTER. You are given three things to choose from here. One, Anything enclosed in parenthesis to a power Two, If you are already given u and f of x And Three, the trig functions with something more than an x involved. I’m demonstrating the third option in this video, the trig function. Enter your trig function. Press alpha first, then the second button, I’m going to do tangent. Three times x squared. I show you what you’ve entered You can change it if you want I say it’s ok You write all of this down on your paper or homework Here’s the formula Here’st he choice for u Here’s what f of u And you’ll notice one over cosine u squared This is an identity for secant squared, the derivative of tan of u Identities, derivatives and integrals of trig functions can all be obtained by going to trig d d x in my main menu And the next screen is the step by step answer Pretty neat huh?

Calculus Help using ti-89 video transcript

This a video on calculus help, many of you have asked for this, this is the ultimate

calculus help program, uhm, this a video for you if you need help in calculus. The instructions

that go along with my programs is the ultimate cheat sheet for you also. When printed out

you are indexed to all that my programs do and they can do quite a bit. All my menu driven

programs are all step by step, and let’s get started here. You’ll notice index8 here

in the entry line of the calculator and you press second alpha, to put in the, uhm, allows

you to put in the letters and then you press alpha to put in the eight and the closed parenthesis,

open and closed parenthesis. Press enter and your into this program here, which is my menu.

And you scroll up or down on my menu and choose the problem you need calculus help with. For

instance, you have graph by hand, implicit differentiation, inflection point, integrals

algebra, integrate by parts, more graphing by hand, intervals of increase or decrease,

limits. You press the clover leaf scroll down button on your calculator to access all these

programs. Let’s do a quick one here. Let’s do product rule for instance, product rule

is when you see a problem and it has a times sign in between two functions , and uhm, quotient

rule would be if you saw a function or a problem and it had a division sign in it, and here’s

the formula for it. And you can enter, you enter it in these brackets here, you put those

in, you have to press alpha first, so your going to have to put that open parenthesis,

and then you cab put, let’s say four times x and then you close off the bracket and put

the new one in, times, lt’s say , three times x squared plus six and close off the

parenthesis, and press enter, it shows you what you’ve entered, you can change it if

you want, I say it’s ok, and then it does the problem for you, and you put all this

down on your paper, or homework, and here’s the answer thirty six x squared plus twenty-four,

ah pretty neat huh? Every step calculus dot come, check it out, check out my programs

and the blog whatever.

Thanks Tom,

I’m having a little bit of trouble using the programs.

For example, I have the following problem I wanted to test out.

Find the derivative of the function using the definition of derivative.

g(t) =

7/sqrt(t)

g'(t) =

State the domain of the function. (Enter your answer using interval notation.)

State the domain of its derivative. (Enter your answer using interval notation.)

I opened F: Definition – derivative and attempted to put in g(t) = 7/ sqrt(t) and get the message “if it appears in a test, nobody would pass the problem: program yet to be completed.

Are there docs that explain how to use each program?

Thank you

Hello Brandon, any time you see a division sign or times sign when thinking of differentiation, first you think of converting somehow to get rid of the division or times sign. In this case the definition of derivative formula is always in x so you need to think maybe of changing the variables. t to x’s so: f(x) = 7/√(x), next since the numerator is only a constant this is not a quotient rule problem, however I realize that you are told to use the definition of derivative to get the answer. You still need to convert before you try that, so: f(x) = 7*x^(-1/2). To find the derivative you’d take the exponent (-1/2) and multiply it times what ever’s in front of the x in this case 7 to get -7/2, then take 1 away from the exponent -1/2 or: -1/2 – 2/2 = -3/2 this will give you -7/2*x^(-3/2), then convert to -7/2/x^(3/2). Now as far as my programs go I haven’t programmed that because I don’t think it would appear on any test. If it did everyone would flunk it probably. Let me know what you think, Tom

Calculus Help: ln(x) differentiating program

Calculus Help: ln(x) differentiating program

Hi Tom,

I found a problem with your ln(x) differentiating program. It always solves g'(x) by saying g'(x)=u’/u, right? But even if u’/u contains a variable, the program will solve u’/u as an integer.

Here are some examples:

If $f(x) = -3 \ln(7 x)$ , find

I calculated using program X:ln(x), option 1: Differentiating

The program uses the Product Rule, and eventually solves for g'(x)

It says g'(x)=u’/u

u’=7

u=7x

g'(x)=2

When g'(x) is actually =7/7x, or 1/x

2. If $f(x) = 5 \ln(6+x)$ , find f'( x )

I calculated using program X:ln(x), option 1: Differentiating

The program uses the Product Rule, and eventually solves for g'(x)

It says g'(x)=u’/u

u’=1

u=x+6

g'(x)=0

When g'(x) is actually =1/x+6

3. If $f(x) = 2 \sqrt{x}\ln(x)$ , find f'( x ) =

I calculated using program X:ln(x), option 1: Differentiating

The program uses the Product Rule, and eventually solves for g'(x)

It says g'(x)=u’/u

u’=1

u=x

g'(x)=2

When g'(x) is actually =1/x

As you can imagine, when g'(x) is wrong,the whole answer is wrong too. Anyhow, fyi.

Thanks,

Sarah

Sarah-

As far as problem 1,

It solves for h ‘ (x) because f(x) and g(x) are in the equation

f(x) = 3

f ‘ (x) = 0

g(x) = ln(7x)

g ‘ (x) = u’ / u = 7/7x = 1/x

Everything seems ok

Calculator gets the same answer

h ‘ (x) = 3/x

Problem 2

There’s always some trick the professors don’t emphasize, so I learned something again

evidently when there is a plus sign or minus sign within the ln ( ) you switch f(x) and the g(x). I did this in my program to update – give yourself a hug

answer

5/(x+1)

Problem 3

Seems to be ok

same answer as calclulator

What Professors don't tell you about ln(x)

October 16, 2012 by Tommy

Any problem with ln(x) in it you’d choose ln(x) in my program menu

When differentiating ln(x) and when using the product rule which is necessary, where the function might be something like 5*ln(6x). You have two functions –—— 5 and ln(6*x). Two functions mean f(x) and g(x).

In my programs I used in this case 5 for f(x) and ln(6*x) for g(x)

And you have the formula for product rule, h ‘ (x) = f ‘(x) * g(x) + f(x) * g ‘ (x)

Don’t worry – I do all of this for you – step by step – in my programs, however I want to mention here of again what professors don’t tell you or make you aware of, and that is

If ln(x) has a + sign or – sign in it, it makes a difference which one you use for f(x) or g(x) so for instance in a function like 5*ln(6x+1), you have to use instead of 5 for f(x) (like above) — ln(6x+1) for f(x)

Now who told you or me about that little detail in our calculus life?

Incidentally any derivative for ln(x) has a special formula which is:

u ‘ / u

u is what’s inside of the parenthesis.

Have fun with my programs and pass calculus, never to use it again !!!

Raw Transcript

This is a video solving a u substitution problem step by step and also demonstrating how my downloadable programs work in your TI 89 Titanium calculator and other TI calculators for calculus and physics problems and let’s get started here to access my programs you have to press second alpha and put the i n d e x letters in here and then press alpha again to put the eight and the open and closed parenthesis press enter you’re into my menu, many things to choose from here as you can see definite integral critical points graphing by hand chain rule we’re going to go up here with the curser to get down to the bottom of the menu which is u substitution and we’re going to put in our function you have to press alpha again to put anything in these entry lines remember to do that alpha let’s go five times x times sign of three times x squared. I always show you what you’ve entered you can change it if you want. I say it’s ok and we’re going to evaluate this of course you have to bring the constants outside the integral which I do for you any time there’s that plus we want to bring this x now over by the x dx to make sure it’s a u substitution problem somehow this inside of this parenthesis has to be made to match this I choose that for you here’s the du you always take a constant out of here and du divided by six and then isolate the x dx which you can see is the same so this is a valid u substitution if it wasn’t it’d be an integration by parts problem. I make sure you know that so I have to ask you this does x equal x it checks whether that is a u substitution problem and here’s your answer you write all of this down on your paper exactly like I’ve got it here you’re bringing constants outside the integral you’re multiplying times what you’ve put outside the integral before, and here’s the answer right here minus five sixths times cosign of three x squared plus c.
