Question

a)State the Green theorem in the plane

(d) Prove part (a) assuming that the domain D enclosed by the simple closed curve
C with positive orientation is of the form
D = {(x, y) | a ≤ y ≤ b, g₁(y) ≤ x ≤ 9₂(y)},
where gi(y), 92(y) are continuous functions, and a, b are some real numbers.
(e) Verify Green's theorem for a vector field F(x, y) = y²i + x²j and a triangle
bounded by the lines x + y = 1 and -x + y = 1 and y = 0.
(Hint: all the conditions in the Green theorem must be verified.)
