[tex]\int[/tex] y2(1 - y3/a2)-2 dy
Upper limit = 0
Lower limit = -a
The Attempt at a Solution
The a's make me really confused and I have no idea how to even start this question.
What I started with was:
Set u = 1 - y3/a2
du = (2y2 - 3y2a)/a3
Then I know you are supposed to make the integral contain only u's, but I am so confused! Am I on the right track? If so, where do I go from here? If not, can someone lead me on the right track?
