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? EveryStepCalculus.com pass calculus and enjoy my programs.
