We give a geometric-trigonometric approach to obtain several identities involving inverse of the functions sin, cos and tan. This provides some new examples satisfying the zero derivative theorem.doi:10.1080/0020739X.2022.2128457Mehdi Hassanimehdi.hassani@znu.ac.ir...
Derivative of Inverse Sine Let us find the derivative of y = sin-1x. By the definition of inverse sine, y = sin-1x can be written as sin y = x. Differentiating this on both sides with respect to x using the chain rule,cos y (dy/dx) = 1...

The derivative of y = arccos xThe derivative of arccos x is the negative of the derivative of arcsin x. That will be true for the inverse of each pair of cofunctions.The derivative of arccot x will be the negative of the derivative of arctan x....
The range of y = arcsec xIn calculus, sin−1x, tan−1x, and cos−1x are the most important inverse trigonometric functions. Nevertheless, here are the ranges that make the rest single-valued. If x is positive, then the value of the inverse function is always a first quadrant ...

The inverse cosine is the multivalued function cos^(-1)z (Zwillinger 1995, p. 465), also denoted arccosz (Abramowitz and Stegun 1972, p. 79; Harris and Stocker 1998, p. 307; Jeffrey 2000, p. 124), that is the inverse function of the cosine. The variants
