Solve it … derivative of cos2x - Wolfram|Alpha. Derivative of cos(2x): (cos(2*x))'-sin(2*x)*(2*x)'-sin(2*x)*((2)'*x+2*(x)')-sin(2*x)*(0*x+2*(x)')-sin(2*x)*(0*x+2*1) 2*(-sin(2*x))-2*sin(2*x) The calculation above is a derivative of the function f (x) 2020-10-08 · The derivative of cos (z) with respect to z is -sin (z) In a similar way, the derivative of cos (2x) with respect to 2x is -sin (2x). We will use this fact as part of the chain rule to find the derivative of cos (2x) with respect to x. How to find the derivative of cos (2x) using the Chain Rule: The derivative of cos2x is -2sin2x. The rules used are : Derivative of cosx is - sinx; Derivative of 2x is 2 ( the answer is given by using chain rule ). derivative of cos2x) full pad ».
