This is a t i eighty nine titanium step-by-step program app for the derivative of cosine of two _x for some function within the parenthesis there to get to my main menu you have to press second alpha to enter the letters i_n_d_e_x and then press alpha again to enter the eight and the left and right parenthesis press enter into my menu you have many choices in this menu of course you can scroll way down all alphabetical equation of a tangent line eliminate the parameter, dot product, cross product, whatever you need here all step-by-step all perfect and we want to do cosine derivative scroll to that uh… you have to press alpha before you enter anything in my programs and so we’re going to enter cosine and let’s enter rather than two _x let’s enter _x squared. 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 uh… 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? EveryStepCalculus.com, go to my programs. Enjoy my programs, and pass calculus.
