This is a video from everystepcalculus.com. Demonstrating how my programs work on a ti89 titanium calculator and other calculators in the TI system for physics and calculus problems I’m going to show you how my programs tackle quadratic formula problems. Let’s get started you have to press second alpha to put i n d e x in here you have to press alpha to put the eight and the open closed parentheses press enter and you are into my menu ahh it’s all alphabetical this menu and all of these choices will help you pass calculus. I’m going to go up with the cursor to get down to the bottom to get to the q section and here’s the quadratic formula and we’re going to do some quadratic formula problems here. I always give you a definition of a problem if I can to help you a little bit about your knowledge of the problem you write this formula down on your paper right away and then we enter the variables you have to press alpha to enter anything into the entry lines of my program entry lines. I’m going to enter alpha minus nine for a going to alpha eight point three for b going to go alpha seven. 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. I’m going to do the step by step version on this one and show you how it does everything it adds the variables here and then it would just like you’d have to do the calculations as you go each screen you mark down the calculations just as you see them and here’s the exact answer and here’s the approximate exact and approximate of that answer pretty neat huh. everystepcalculus.com go to my site buy my programs and pass calculus.
