I know I need to find a Leibnitz formula for derivative of product, but how? Also Well if you calculate the first derivative properly you should be yielded to -2sin(2x ). Edit: Take into consideration that the derivative of cos(Ux)=  For instance, ddx(tan(x))=(sin(x)cos(x))′=cos(x)(sin(x))′−sin(x)(cos(x))′cos2( x)=cos2(x)+sin2(x)cos2(x)=1cos2(x)=sec2(x). Before watching the video,  10 Oct 2017 Given: y = cos(2x). Let y⁽ⁿ⁾ denote the n-th derivative of y wrt x. The first few derivatives of y wrt x are the following: n=1: y⁽¹⁾ = - 2¹ sin(2x) How do you integrate Cos 2x?

The derivative of tan x is sec2x. Now, if u = f(x) is a function of x, then by using the  50 th derivative of y=−250cos(2x) · More Answers · Discussion · Watch More Solved Questions in Chapter 3 · Video Transcript.
