  1. May 28, 2012 #1
    1. The problem statement, all variables and given/known data
    x*y2(dy/dx)=y3-x3
    solve the problem

    2. Relevant equations



    3. The attempt at a solution
    My answer was (x3/3)+c=y/x
    there is no answer in the back of the book for this one so i just want to make sure i got it right

    Solve your result for y. Then, take the derivative & plug it into the given equation. See if you get equality.
