1. The problem statement, all variables and given/known data I have exam tomorrow and there's a problem I don't know how to do. Consider the curve C1 (x=-y^2+3y) and C2 (x=0), both defined for y[itex]\in[/itex][0,3]. Calculate the work done by F(x,y)=(x,y^2) along the curve C=C1UC2 (retrograde direction). 2. Relevant equations 3. The attempt at a solution The solution given is 0. I really don't know how to get it. Thanks!
