Thanks!

Okay, I've lost you. I see that you've brought a 1/4 to the outside by squaring 4x^2, but how come the range of the integral also changes?

Also, how do I use sin to solve the rest of the problem?

I don't mean for you to simply solve the problem for me; I simply want to follow how you're getting to that point.

Thanks so much.

**You should notice that this is an improper integral, it should be solved in terms of limits ..**
