Our f would look like this in this situation. f is f of xy is going to be equal to x squared minus y squared i plus 2xy j. We've seen this in multiple videos. You take the dot product of this with dr, you're going to get this thing right here.
WebBy Green’s Theorem, I = Z C ydx−xdy x 2+y = Z C Pdx+Qdy = Z Z D ∂Q ∂x − ∂P ∂y dxdy = Z Z D x 2−y (x 2+y 2) − x2 −y2 (x +y2)2 dxdy = 0. (b) What is I if C contain the origin? Solution: The functions P = y x 2+y2 and Q = −x x +y2 are discontinuous at (0,0), so we can not apply the Green’s Theorem to the circleR C and the ...

Tags green; vector; tshirt vinyl sizesWebHere is a clever use of Green's Theorem: We know that areas can be computed using double integrals, namely, ∫∫ D1dA computes the area of region D. If we can find P and Q so that ∂Q / ∂x − ∂P / ∂y = 1, then the area is also ∫∂DPdx + Qdy. It is quite easy to do this: P = 0, Q = x works, as do P = − y, Q = 0 and P = − y / 2, Q = x / 2. phil stephani
