Verify Green’s theorem for taken around the rectangle bounded by the lines x = ±a, y = 0 and y = b.

Answer»

Answer:

BASIC ALGEBRA Identities

(a + b)2 = a2 + b2 + 2AB

(a – b)2 = a2 + b2 – 2ab

a2 – b2 = (a + b)(a – b)

a2 + b2 = (a + b)2 – 2ab = (a – b)2 + 2ab

a3 + B3 = (a + b)(a2 – ab + b2)

a3 – b3 = (a – b)(a2 + ab + b2)

(a + b)3 = a3 + 3ab(a + b) + b3

(a – b)3 = a3 – 3ab(a – b) – b3
