WebThe derivative of the cosine function is written as (cos x)' = -sin x, that is, the derivative of cos x is -sin x. In other words, the rate of change of cos x at a particular angle is given by -sin x. Now, the derivative of cos x can be … WebThe derivative of cos square x is equal to the negative of the trigonometric function sin2x. Mathematically, we can write this formula for the derivative of cos^2x as, d (cos 2 x) / dx = - sin2x (which is equal to -2 sin x cos x). The derivative of a function gives the rate of change of the function with respect to the variable.
