I have a feeling I should know this, but what's the method for finding the integral of functions like

$\displaystyle \int \frac{1}{\sinh x + 2\cosh x} \, dx$

This is easy is it were regular trigonometric functions (using the famous tan substitution) but how do we approach these one?

No need to solve the problem, I'm just asking about the method
