Green's theorem proof
WebUsing Green’s formula, evaluate the line integral ∮C(x-y)dx + (x+y)dy, where C is the circle x2 + y2 = a2. Calculate ∮C -x2y dx + xy2dy, where C is the circle of radius 2 centered on the origin. Use Green’s Theorem to … WebThis is the boundary. This is the boundary of our surface. So this is c right over here. Stokes' theorem tells us that this should be the same thing, this should be equivalent to the surface integral over our surface, over our surface of curl of F, …

WebUse Green's Theorem to calculate the area of the disk D of radius r defined by x 2 + y 2 ≤ r 2. Solution: Since we know the area of the disk of radius r is π r 2, we better get π r 2 for our answer. The boundary of D is the circle of radius r. We can parametrized it in a counterclockwise orientation using c ( t) = ( r cos t, r sin t), 0 ≤ t ≤ 2 π.
