    What are you stuck on? c: Is the pi/2 confusing you?

    Think about the derivative for a sec, If you took the derivative of this term, you'd have to apply the chain rule. The derivative of the inside would give you an extra pi/2 on the outside. When we integrate, the opposite should happen :D We'll divide by that coefficient to compensate for the pi/2 that would normally show up due to the chain rule.

    If you're not quite convinced, you can do a `U sub` I suppose :)
