WebOct 7, 2024 · 1 Answer. Sorted by: 0. That's because, the double integral is over a square and not and ellipse, you have to use the equation of the ellipse: x 2 16 + y 2 3 = 1. You find that the curve is between: y = ± 1 − x 2 16. Then you're x is between − 4 and 4, that is where you get your π. Share. WebNow we just have to figure out what goes over here-- Green's theorem. 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.

WebLecture21: Greens theorem Green’s theorem is the second and last integral theorem in the two dimensional plane. This entire section deals with multivariable calculus in the plane, where we have two integral theorems, the fundamental theorem of line integrals and Greens theorem. Do not think about the plane as WebHere we’ll do it using Green’s theorem. We parametrize the ellipse by x(t) =acos(t) (4) y(t) =bsin(t); (5) for t2[a;b]. Then Area= ZZ D 1dA = Z 2ˇ 0 x(t)y0(t)dt = Z 2ˇ 0 acos(t)bcos(t)dt …
WebGreen’s Theorem Formula. Suppose that C is a simple, piecewise smooth, and positively oriented curve lying in a plane, D, enclosed by the curve, C. When M and N are two functions defined by ( x, y) within the enclosed region, D, and the two functions have continuous partial derivatives, Green’s theorem states that: ∮ C F ⋅ d r = ∮ C M ...
