This is a video from everystepcalculus.com demonstrating how my programs work on a TI -89 titanium calculator and other calculators in the t i system for physics and calculus problems. Let’s get started to access my menu you have to press second alpha to put the i n d e x in here and then you press alpha to put the eight and the open and closed parenthesis press enter and you’re into my menu. We’re going to go up with the cursor to go down to the bottom you’ve got u substitution trig and half angles quotient rule but we’re going to do quadratic formula right now. I give you some sort of definition there of it write the formula down on your paper right away and we’re going to enter our variables you have to press alpha before you enter anything into my entry lines here. Alpha minus seven alpha three and alpha four I show you what you’ve entered so you can change if you’ve made a mistake I say it’s ok and we’re going to do the quick answer here for calculus formula calculator which this is here’s the variables entered into the formula that you wrote before on your paper and here’s the answer exact answer exact answer and approximate answer pretty neat, huh? everystepcalculus.com go to my site.
