Calculating the nth Derivative of Cos(X) Physics Forums

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 calculated using different methods. It can be derived using the limits definition, chain rule, and quotient rule.
