I'm having trouble integrating this function:
So far I've tried substitution and that didn't work out so well. Please help!

Ok, I made the double angle substitution, but I'm still drawing a blank on how to get this one started. Which method of integration should I use?
Better yet, note that .
Ok, I've used the trig identities to change the integral to this:
I think what is throwing me off is the fact that this function is under the radial. At this point, would substitution work if I use ? Is this the correct integration method to use?
Scrap that substition, it will not work. Which method of integration do I need to look at?
I think I might have found the solution. The problem is actually a definite integral problem with the lower limit of integration as 0 and the upper limit of integration as pi/2.
I've worked the problem out and came to a solution of -2. Is this correct?
Its a gimmie from here!
