So the curve C is a triangle with base of 2, height of 2 and is parameterized by {x[t],y[t]} in the counterclockwise direction.

Use the Gauss-Green formula to evaluate the path integral:

*Integral C* [E^(-x^2)+x y^2]dx + [x^3+ sqroot(1+y^3)]dy

I'm completely stuck because I'm not sure how to get all the x's and y's in terms of t, which should be the first step I'm guessing.

I have many problems to do just that are similar to this one. Could I please get a step-by-step so I can apply to others? That would be awesome
