16 нояб. 2022 г. · So, the derivative of the inverse cosine is nearly identical to the derivative of the inverse sine. The only difference is the negative sign.

To prove any inverse trig derivative, we use the chain rule. For example, to find the derivative of cos-1x, we assume that y = cos-1x from which we get cos y = ...

To prove these derivatives, we need to know pythagorean identities for trig functions. Proving arcsin(x) (or sin -1 (x)) will be a good example.
