We can find the inverse function as follows
To find the derivative of the inverse function
Switch x and y.

Because x and y are reversed to find the
reciprocal function the following pattern always
holds
is equal to the reciprocal of

Your calculator contains all six inverse trig
functions. However it is occasionally still
useful to know the following
