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
