TransendentialPI
Group Title
This exercise is in a section about using trig substitution to integrate. I can use trig sub, but I'm just not seeing what initial substitution to use so I can apply trig sub. Can anyone give me a hint? I don't need (don't want) it solve to the end. At least not yet.

The trick is, how do we get this integral into the form\[dx \over \sqrt{u^2 +a^2}\]
