Solve the Equation: ln(x+2)=3
Hello, again. Tom from everystepcalculus.com and everystepphysics.com. I’m going to do a, solve a natural log equation right no, on the Titanium. I’ll show you my program work on that. Index 8 to get to my menu. I’m already at the scroll down to log of x solved. Press enter and number three. Choose number three solving. You have to go through the menus. We’re going to enter the function. You have press Alpha before you enter anything into these entry lines, here. Alpha second log of X plus 2 equals 3. I always show you what you’ve entered, in programs, you can change in case you made a mistake. I say it’s okay. You’re going to multiply both sides by E. And when you multiply a log times E, you get X plus 2 simply. These are all simple but try to remember that during a test with the other any number of equations and rules you have to memorize to place into a calculus test. Pretty neat, huh? everystepcalculus.com. Go to my site, buy my programs if you want to pass calculus and subscribe so you can see more videos.Have a good one.
What is the integral of ln(x^2+2*x) dx?
This is a video from everystepcalculus.com. Demonstrating how my program work on a ti 89 titanium calculator and other calculators in the ti system for physics and calculus problems now I’m going to demonstrate log problems ah with regard to my programs to enter the code to get into my menu you have to press second alpha and put i n d e x in here and then press alpha and the put the eight and the open and closed parenthesis press enter and you’re into my menu this is all alphabetical in my menu you scroll down to log problems in the l section there it is there and you have all these different things you can do with log problems right now I’m going to differentiate so I’m going to press number six you can scroll down or use the number here in the front I’m going to press number six give you the option of doing log to the base some other base or the natural log I’m going to do natural log first here and were going to enter our function you have to press alpha before you enter anything into the entry lines of my programs here your going to press alpha and then were gonna press second to enter the log function you have to add the ln there and let’s do it. six times x squared plus nine. I always show you it factored it here calculator did that automatically I always show you what you’ve entered so you can change it if you want I say it’s ok. And y is equal to log of some function in here f of x and here’s the function and the formula is y prime is equal to f prime of x divided by the function itself I show you the function. I show you the derivative of it taken the derivative and dividing it by the answer and ahh, the original function and her’s the answer four x divided by two x squared plus three. Pretty neat huh, everystepcalculus.com. Go to my site buy my programs and pass calculus.
This is a video from EveryStepCalculus.com demonstrating how my programs work on a TI-89 Titanium calculator and other calculators in the TI system for physics and calculus problems. This is an example of finding the derivative of natural log in my calculus programs and let’s get started in my programs you have to push second alpha to put in the letters i n d e x and then press alpha to put the eight and the open closed parenthesis and press enter and you’re into my menu you’ll scroll down to log of x derivatives and you want to differentiate it so you choose that you can integrate it or solve for x also and we’re going to enter a function here you have to press alpha before you enter anything into my entry lines here So we press alpha. I’m going to press second and then log and let’s put in ah six times x squared plus seven. I always show you what you’ve entered so you can change it in case you made a mistake. I say it’s ok and we’re finding the derivative
of log of six x squared plus seven the formula is u prime over u u being what’s inside the parenthesis here
here is u here six x squared plus seven the derivative the derivative of that excuse me is twelve x and u prime over u so here’s the answer twelve x divided by six x squared plus seven ahh pretty easy if you know the formula and, but my programs show it step by step easily like this. Pretty neat, huh? EveryStepCalculus.com

How the calculus calculator (TI89) solves the Natural Log:
~ Bring up the menu and scroll to natural log
~ Enter functions by pressing alpha before
~ Enter your range
~ Program will review and ask for changes
~ It will substitute the lower limit of your function
~ It substitutes upper from lower and produces answer all step by step
