Hi
Through
Then you can use
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.
