I have been working out some cases where I can't integrate through trigonometric substitutions (or at least, not easily) but I can using hyperbolic functions. See if you can solve

$ \int x^2\sqrt{x^2+1} $

Special points if you can solve it using trig functions.

The method and thought process

Identities you will need
