Green's Theorem : Evaluating a Line Integral

Please see the attached file for the fully formatted problems.

Use Green's Theorem to evaluate the line integral Sc xy dx +x^2y^3 dy where C is the triangle with vertices (0,0), (2,0) and (2,2).


Solution Preview

I = integration (along C) [x*y*dx + x^2*y^3*dy]

By Green's theorem,
integration(along C)[f1*dx + f2*dy]
= integration (over region E) [ del(f2)/del(x) - del(f1)/del(y)]dx*dy

f1 = x*y => del(f1)/del(y) = x,
f2 = x^2*y^3 => ...
