I have this exercise which asks me to calculate the circulation of a velocity field on V over the indicated path, this is it:

$\displaystyle \vec{V}=xy^2 \hat{i}+xe^{xy} \hat{j},y=x^2,x=0,y=1$

The thing is I don't know if I must use the path $\displaystyle y=x^2$ from (0,0) to (1,1), or if it reefers to three different paths with $\displaystyle y=x^2,x=0,y=1$ In that case I wouldn't know which extremes to use in the line integral. And the exercise that follows its similar, it gives a path, but it don't tells from where to where, but I think that in that case could be because the path is closed.

Bye and thanks!
