this is a TI-89 titanium step-by-step program app for the derivative
for some function within the parenthesis there
to get to my main menu you have to press second alpha to enter the letters
and then press alpha again to enter the eight and the left and
press enter into my menu
you have many choices in this menu of course
you can scroll way down
equation of a tangent line
eliminate the parameter, dot product, cross product, whatever you need here
and we want to do
scroll to that
uh… you have to press alpha before you enter anything in my
and so we’re going to enter cosine
and let’s enter
rather than two _x
let’s enter _x
I show you what you’ve entered so you can change it
and i say it’s okay
give you the chain rule formula, you write all of the
things down step-by-step calculations
on each screen
so you can get an _a in calculus
derivative of cosine of
_u is minus sine of _u
and here’s your answer
two times _x minus sine of _x squared
pretty neat huh?

I showed my ex, who is a calculus professor, and he was waaaaaaay impressed. And he is an arrogant ass, who never helped me ever...I could tell he wanted to hate on it, but he couldnt. -- Kristin P
Tom…I think that I’m finally done with Calculus II. In the prior test I got 78 and yesterday I finished all the problem on the test. I think I should be able to remain around the same grade. Thank you so much for your help; your programs really made the difference. They didn’t just solve the problems for you, in my case, they gave me the confidence and security I had lost with those stupid professors and the way they teach. To be honest, studying the programs on my calculator taught me how to solve problems that I couldn’t do before due to the way they were presented. I felt confident and secure yesterday, and it only possible because either I remember how to do the problems or the calculator would. Thanks one more time for time, dedication and quick responses. There is no other person in the whole world that would do what you do for us , college students being killed with freaking calculus classes. John
AWESOME!! It works great. You have the best support. Thanks!!
