SUMMARY

The discussion focuses on applying Stokes' Theorem to compute the line integral of the vector field F(x,y,z) = (-z², y², x²) over the curve C, defined by the intersection of the plane -y + z = 0 and the paraboloid z = x² + y². Participants noted the importance of correctly calculating the curl of the vector field and suggested using the plane for easier computation. The confusion around the expression '-2x-2xj' was clarified, emphasizing the need for accurate notation in vector calculus.

'-2x-2xj' makes no sense. And if you intended '(-2x-2x)j', that is 0.

Since the curve is given as the intersection of the two surfaces, you can use Stoke's theorem on either surface. I imagine the plane would be easier.
