(a) R C (y + e √ x)dx + (2x + cosy2)dy, C is the boundary of the region enclosed by the parabolas y = x2and x = y . Solution: Z C (y +e √ x)dx+(2x+cosy2)dy = Z Z D ∂ ∂x (2x+cosy )− ∂ ∂y (y +e √ x) dA = Z1 0 Z√ y y2 (2−1)dxdy = Z1 0 ( √ y −y2)dy = 1 3 . Web6 Green’s theorem allows to express the coordinates of the centroid= center of mass Z Z G x dA/A, Z Z G y dA/A) using line integrals. With the vector field F~ = h0,x2i we have Z Z G x dA = Z C F~ dr .~ 7 An important application of Green is the computation of area. Take a vector field like F~(x,y) = hP,Qi = h−y,0i or F~(x,y) = h0,xi which has vorticity … In vector calculus, Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C.
