Question

How do you find `int sec^2x`?

Answer 1

`tan (x)+c`

Explanation:

Integrating requires you to find the function that you have to differentiate in order to give the function that you're integrating.

In the case of `int sec^2 x`, the function that, when you take the derivative, gives you the function `sec^2 x` is `tan x +c`.
