this is a TI-89 step-by-step program app for the derivative

of sin2x

or some function within the parentheses

to get to my main menu you press second alpha

to enter the letters i_n_d_e_x and then press alpha again to enter the

8 and the open and closed

parentheses

press enter and your into my menu

you scroll to where your choice is

in this calculus calculator program app

i'm demonstrating how to solve step-by-step the derivative of

sin2x

you can see the choices here of on some my menu many many things projecting A on B

quadratic formula, quotient rule relative extrema, that's graphing by

hand

but we're going to do the derivative of sin2x

here

so we go down to sine of A to the X derivative

and press enter

you can do cosine or sine

we're going to enter the function you have to press alpha before you enter

anything in my programs

and so we're gonna do

sine of

five

times

x

press enter

I show you what you've entered

corrected if you want to say it's okay

I give you the chain rule formula

you write this stuff all in your paper to get the step-by-step calculations

U equals five x etcetera

derivative of f of u sine of x cosine of u

and so you have your answer here five times cosine of five x

pretty neat huh?
