9 vertices (0, 0), (,0) and (l, l). (a) Evaluate the integral 3. Let be Let C be the triangle with [a³y da - xy dy by direct calculation. Hint: You will need to evaluate three different line integrals. A diagram will be useful! (b) Now evaluate the integral a³y da - ry dy using Green's Theorem. (You should find this much easier!).
