Green theorem matlab
WebMar 24, 2024 · Green's theorem is a vector identity which is equivalent to the curl theorem in the plane. Over a region in the plane with boundary , Green's theorem states (1) where the left side is a line integral and the right side is a surface integral. This can also be written compactly in vector form as (2) 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 ...
