Derivative of cos is

WebJul 31, 2016 · Since cos(2x) = cos2(x) −sin2(x), we can rewrite this using the Pythagorean Identity to say that cos(2x) = 2cos2(x) − 1. Solving this for cos2(x) shows us that cos2(x) = cos(2x) + 1 2. Thus: ∫cos2(x)dx = 1 2 ∫cos(2x) + 1dx We can now split this up and find the antiderivative. = 1 2 ∫cos(2x)dx + 1 2 ∫1dx = 1 4 ∫2cos(2x)dx + 1 2x WebThe derivative of cos inverse can be determined by implicit differentiation. The derivative of a function represents the rate of change of the function at some point. Since the derivative of cos inverse x is -1/√ (1-x 2 ), therefore the graph of the derivative of arccos will be the graph of -1/√ (1-x 2 ). Derivative of Cos Inverse Formula
