sin2x cos2x Video Summary
How the TI-89 solves sin2x cos2x:
~ Bring up the menu and scroll to derivatives of sine and cosine
~ Enter functions by pressing alpha before
~ Program will review and ask for changes
~ Shows the chain rule formula
~ Program produces answer all step by step

This is a TI-89 Titanium step-by-step program app for sin2x cos2x to get to my main menu you have to press second alpha and the letters i_n_d_e_x and then press alpha again for the 8 and the left and right parentheses press enter and your into my menu you can scroll up or down many many things on this program parametric equations log of x would demonstrate sine and cosine of the derivatives of sine and cosine, let’s try it you have to press alpha before you enter anything in my programs my step by step sin2x cos2x programs and your going to enter and say cosine of 5
times x cubed, I show you always what you’ve entered so you can change it if you want if you make a mistake or whatever I say it’s okay here’s the chain rule formula you write all these calculations down on your paper step-by-step just like i’ve shown you here for you A in this problem all of this is required compute the answer and here’s your answer fifteen x squared minus sine of five x q
lets do a new problem alpha sin of two times x answer to cosine of 2x pretty neat huh? EveryStepCalculus.com go to my site check out my programs. Pass calculus.
