# How to integrate sec^2(x)/tan(x).

Integration is the opposite of differentiation. Now to integrate a given function, we look for the derivative of the given function. For instance how to integrate sec^2(x)/tan(x).

\text{find the integral of }\space\int\frac{ \text{sec}^2x}{\text{tan}x}dx\\
Hence: \text{integral of }\space \int\frac{sec^2(x)}{tan(x)}dx\\=ln\space\text{tan(x)}+c, \\\text{where c is a constant}
