This is a video from everystepcalculus. com demonstrating how my programs work on at TI-89 titanium calculator and other calculators in the TI system for calculus and physics problems. Okay log differentiation. Let’s get started to get into my menu, you have to press 2nd alpha i n d e x letters Put them in and then press alpha five. Put open and close parentheses I’ve already scrolled down the log of x that derivative. Which is what you want so then press enter. You want to differentiate, you dont want to integrate, we don’t want to solve for x which we can do. We’re going differentiate right now. Then we have to press alpha before you enter anything out of these entry lines in my programs. I always show you what you’ve entered so you can change in case you’ve made a mistake. I say it’s okay. And here’s the system differentiate log of x to the fourth. And you’re going to find, u prime equals four time x cubed. When you have four x cubed over x to the fourth cancel out and the answer is four over x. Pretty neat, huh. Go to my site, buy my programs and pass calculus.
