U Substitution 6*x^2/(x^3+1)^5 on TI-89 | Every Step Calculus Video
Raw Transcript
Ok a video on u substitution with regard to a division function. Let’s get started you press second alpha put the i n d e x letters in you need to press alpha again to put the eight and the open and closed parenthesis press enter and you’re into my menu. I want u substitution which is at the bottom it’s all alphebetical here. So I’m going to go up with the cursor which goes to the bottom and choose u substitution I’m going to enter my function which is press alpha first on anything you enter into my entry lines in my programs press alpha and we got six times x squared divided by the quantity x cubed plus one to the fifth power always use plenty of parenthesis especially in division so they know exactly what your doing what your dividing by very important I show you what you’ve entered in case you’ve made a mistake but I say it’s ok. I press ok I always rewrite things notice you have a constant here you have to bring it outside the integral here it is here times the integral and then you take the x squared what’s left and bring it to the end here where they have dx x squared dx and u equals what’s inside the parenthesis x squared plus one du equals three x squared or that’s x cubed, sorry etcetera you always bring the anytime there is a constant in front of the x or whatever you get here you always divide du divides by three by that and I always ask you if x squared equals x squared. I can’t do it automatically in the calculator and so I need to ask you that if it wasn’t a u substitution problem this would be different and would be integration by parts so u to the minus five is equal to x to the minus five and you do these calculations on your paper put it all down exactly like this and here’s your answer minus one x cubed plus one to the fourth power plus c. Pretty neat huh? everystepcalculus.com. Buy my programs

U-Substitution on the TI-89: 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 uhm second alpha i n d e x the letters
and you press alpha to put eight and open and closed parenthesis
press enter and you’re into my menu you can scroll down or up to that u substitution
it’s all alphebetical and we’re going to get to u substitution here
enter our function you have to press alpha before you enter
anything in the entry lines here and we’re going to do
two times x times the
square root orange key
and then the over the times key x squared plus nine
press enter I always show you what you’ve entered
in case you’ve made a mistake I say it’s ok
and here’s your function we’re going to have to rewrite it
here’s the constant you have to take it outside the integral sign
take the x and put it over here by the dx and u equals x squared plus nine
and here’s the derivative anytime you have a constant here
you have to put it over and divide du by that constant
and leave the rest over here should be no numbers over here
notice this is the same as the previous x by dx
that’s why we rewrite it here’s the calculations
put em all down on your paper exactly like this
pretty complicated but when you take you notice when you have a square root
it’s to the one half and so therefore you’re using u to the one
half and you have to add one to that
which will be two halves which equals three halves and then
you have to divide by three halves that’s the way you integrate
and then of course don’t forget to uhm when you’re gonna when your dividing by
a fraction you always have to invert and multiply
here’s two thirds inverted from three halves or three over two
then you substitute back in for u and here’s your answer here

U Substitution Integration 5x*e^(3x^2) on the TI-89 Video
U-Substitution Integration on the TI-89: Raw Transcript
This is a video on u substitution with regard to e to the x
a transcendental function and a little more difficult one
which I wanted to show you of how my programs react to that
to get started were going to press second alpha
put the i n d e x letters in this entry line of the calculator
and then press alpha and put in the eight and the
open and closed parenthesis press enter and you’re into my menu
you can scroll up or down to many things here it’s really integration by parts that your
always thinking about when you do a transcendental cosign sign natural log or
e to the x if you’re going to integrate them you’d go to think integration by parts first
but we’re going to scroll up to e to the x here
choose e to the x from that menu and we’re going to enter the function
you have to press alpha before you enter anything in the entry lines of my programs
so alpha and we’re going to do five times x times e to the three times x
squared I always show you what you’ve entered
so you can change it if you’ve made a mistake or something
and I always ask you whether this if this didn’t equal each other then it would
not be u substitution so you need to tell me that
by stating yes or no it does equal, x equals x so were going to
press yes and then I explain to you that anything inside
the parenthesis of e to the x
the derivative must match the outside and so here’s our original function
we re write it anytime you have a number or a
constant inside the integral you always bring it out and put it on the outside of
the integral before you start to integrate
which I’ve done here you take what’s left the x
and put it over here in the x dx so thats re writing it
and I choose the u for you. here is the derivative of three x squared
it’s six x and then you always take here’s another thing where
there is a constant or number is outside or next to the x dx
you always put that on the other side make du one sixth du equals x dx
transpose it by division and then you do everything
all this on your test or homework whatever exactly correct exactly as you see it
here we’re multiplying the outside of the integral
times the du of the one sixth comes of du comes out side too
gives us five sixrths and then you substitute three x squared for
u answer
five sixths times e to the 3 x^2 plus c pretty neat huh

U Substitution Integral x^2/(x^3+1)^2 | TI-89 Video
U-Substitution Integral on the TI-89: Raw Transcript
This video is on u substitution uhm with regard to calculus
for your tests and homework and let’s get started
you have to press second alpha first to put the letters i n d e x in here
then press alpha and put the eight and the open and closed parenthesis
press enter and you’re into my menu I’m already at u substitution
but you can see there’s many many things in here
for you to pass your calculus tests and do your homework
I was never really interested in learning this stuff
I just wanted to know how to do it for my tests and homework
ah, but were going to do u substitution that’s the way my programs are designed
all of my programs including my physics programs
uhm u substituion lets put the
you have to press alpha before you put anything in the entry lines
here in my programs
so I press alpha and let’s put in x squared divided by the
quantity one plus x cubed to the second power
I always show you what you’ve entered so you can change it in case you’ve made a
mistake I say it’s ok
we’re going to evaluate x squared divided by x cubed plus one over two
and we rewrite the program to put the x squared over by the dx here
and of course there’s one in the numerator there
and we choose, i tell you what to choose to isolate the x you take the three and move it to the other
side for the du du divided by three equals x squared dx
and then we of course change the function to u
1 over u squared same thing as one over what you entered there
and you do the calculations notice that we have du divided by three
but you always take a constant or fraction and move it to the front of the integral sign
here which I’ve done for you
and then you have you have to change u two to the numerator
you can’t integrate with a division or times sign
you have to change it to a single numerator and so we have u to the minus two
and you add one to that which becomes a minus one
and you get one third over one to the minus u
and etcetera and here’s your answer uhm pretty neat huh

U Substitution Definite Integral on TI-89 | Every Step Calculus Video
Definite Integral Example on the TI-89: Raw Transcript
This is a video on u substitution and this one is about a definite integral
where when you actually compute the integral you are going to compute it over a range
with a lower limit and a upper limit so anytime you have a problem like I’m going
to show you here that’s the way you use my programs
you go to u substitution let’s get started here
we’re going to press 2nd alpha and put i n d e x
into the entry line of the calculator then press alpha and put the eight and the
open and closed parenthesis press enter and you’re into my menu
you have many, many things on here notice graphing by hand
and all kinds of things that are perfectly done
and wonderfully done on these programs to help you with your tests and homework
and that’s what we’re interested in is passing calculus
and never to do it again so anyways you can scroll up or down
to u substituion this is all alphebetical and this case you
want u substitution so we might press the upper cursor to go up
and to the bottom menu, which is u substituion
notice you have trig d dx integrals for trig
half angle formulas all kinds of things you need for calculus
one for sure and then I have other programs for calculus
two and three so if I press enter we’re into u substitution
and generally you press alpha and put your function in here
you have to press alpha first and then put the function in
but I’ve already done that to speed up the video so i’m going to
I always show you, this is the function we’re doing
I haven’t put the limits in yet so you have to recognize that
you are going to do the integral first and then at the end I ask you if you want
to do the range for the area or limits
now, I always show you what you’ve entered so you can change it if you want
I say it’s ok and we’re going to evaluate this integral
here now you’ll notice that the derivative of three
x to the five is really fifteen x to the four
and here’s an x to the four so if you didn’t have my calculator
that is what you are really looking at everytime you look at an integral
you say well is the inside, can you do the derivative
to make it equal to the outside somehow and
but I do that for you in my programs we always rewrite it
anytime you have a number or constant inside the integral
you take it outside the integral like I’ve done here in my programs
and then you evaluate the integral inside but also when you rewrite it you need to take
this x to the four and put it over here by the
dx and then you choose the u which is the three
x to the five plus two and the derivative of that is fifteen x to
the four anytime you have a number here before the
x you need to transpose it to the other side
by division so you are going, which I’ve done here now
du divided by 15 equals x to the four dx you’ll notice that this equals what we re-wrote
in the beginning here and so we know that that is a u substitution
problem and I ask you that too
because I need to check that before and so I ask you if x to the four equals x
to the four if it says yes, if they’r equal you say yes
of course if it’s not equal you say no if you say no then you are into log rhythms
because in integrals you can’t do integrals with a times sign or
division sign you need to seperate it into plus and minus
parts so that you can integrate it
and that’s what log rhythms do for instance in times you are taking a log
of one factor plus the log of the other factor in division you are taking the log of one
factor minus the other.
so anyway they are equal so we’re going to get on with this
you write all of this on your paper and write it kind of sloppy
students and people that really know this stuff write sloppy
that’s been my experience, including professors they scribble because they want to make everyone
know that they are genius’s at this stuff.
so you do the same don’t write it clean like this write it sloppy
and uhm, here’s the answer after you do all the u
you’ll notice the du divided by fifteen you need to bring that to the outside of integral
which I do one fifteenth times six here
multiply that together to get two fifths and then you do the integral of u to the 6
which you add one to the six and get seven and divide by seven
u seven divided by seven well then you have to do the computation there
seven times five is thirty five so you have two over thirty five
now you substitute back in the u which is thirty five plus two
and you have your answer plus c now the really tricky part here
I ask you if you want to evaluate the range you can press one here and do it
let’s do the limit which I’ve put in there as number one
for the lower range or limit and number two for the upper limit
and so here’s the integral that I showed you at the
beginning of the video. which is called a definite integral
where you find the area under the curve and again if there is a mistake in adding
the limits I ask you that so you can change them if you
want now you’re going to substitute
if x equals one then u equals
remember we’ve decided that u equals this and then you add the one in there and mulitiply
it out to get five ok?
if x equals two you put this exactly on you paper, here’s
what your doing u equls three x two
and that equals ninety eight so you have u substituted here and you have
the upper limit ninety eight and five notice you can’t use one and two for the limit
because you’ve changed it to the u system, so
and then with u equals ninety eight the upper limit
you have to go back to the original function and put it in here the original integral that
you’ve found and that equals four point nine six times
e to the twelve and then when, the lower limit is five so
you are adding that into the original u funtion to get four point four three time e to the
3 you substract the upper limit
the lower limit from the upper limit here’s the area under the curve
four point nine six times e to the twelve square units
uhm, notice how fabulous these programs are and how they will help you so much
even in learning this stuff let alone passing tests
or for homework so you can buy my programs at

Integration by Parts on the TI-89: Raw Transcript
Okay this
videos on integration by parts with regards to sin(x)
let’s get started 2nd Alpha
enter my code for my menu
i_n_d_e_x
if you watch my other movies your used to this
but it’s always good to review. Alpha again 8 and closed parenthesis
and again your into my menu
we have integration by parts, length of an arc, limits
line integral, all in alphabetical order
so you can do anything you want here. We’re going to goto integration by parts,
with regard to sin(x)
I’ll give you an example of what you might want to put in there.
We’re going to put in…you have to press Alpha
before we put anything in these entry lines here.
We’re going to go x
times and then we have to go the second to get to the sin
function
And let’s go 3 times x.
And let’s press ENTER twice and it shows you what we have entered we can change it
of course, I say it’s okay, and we’re into the
equations or into the solving of it. OK, here’s the original function
you choose dv.
and v is equal to the integral of sin of 3x
dx that equals minus cosine 3x divided by 3
and then u is going to be x
and then du is going to be 1(dx)
here’s the original function again, here’s the formula, v times u minus the integral
of v times du dx
so we add this, v is equal to minus cosine 3x over 3, and u is equal
to x. We have the integral of d, which is minus cosine of
3 of x
divided by 3 and times du one
and we work it out write this stuff all on your paper
as your doing your problem.
Exactly as you see it. Here’s your answer equals a minus x cosine 3x divided by 3
plus sin of 3x over 9 plus C.

and we’ll put in three times x
this is right off a test here now two and the left parenthesis for the other
function five times x cubed minus x squared plus one

I’ve showed you what you’ve entered you can change it if you want

but right now I want to get to product rule so I’m going to scroll up to product rule
I show you the formula make sure you write everything down
on your paper just like you see it here you get extra credit
and you get certain partial credit for everything so
ahh you have to press alpha before you enter anything into
my menu lines here so let’s put
alpha x squared times the gold key ya know tangent let’s say two times x
press enter I always show you what you’ve entered
so you can check it if you want and change it if you want
but I say it’s ok and we’re into the menu
notice it converts tangent to the identity and this is always fun to
put this down on your test and get a hundred percent on it
