What is the derivative of tan

what is the derivative of tan

So we have proved that exists and

.

Similarly, we obtain that

exists and that

.

Since

,

,

, and

are all quotients of the functions

and

, we can compute their derivatives with the help of the quotient rule:

It is quite interesting to see the close relationship between

and

(and also between

and

).
