# Math Help - green theorem or stokes????

1. ## green theorem or stokes????

Hi,I dont think this is the normal integral.
∫(x²-2xy)dx+(x²y+3)dy where c is boundary of region defined by y^2=8x and x=2 traversed in counterclockwise direction.
Thanks.

Hey n22.

Since this is a line integral, you need to parameterize the curve first and then use the results of vector calculus for line integrals:

Green's theorem is for plane areas while stokes is for general surface, which make green's theorem a special case of stokes'theorem. both relates the surface integral of functions to line integral of the line that encompasses that surface.
