WebGreen’s Theorem as a planimeter Bart Snapp A planimeter computes the area of a region by tracing the boundary. Green’s Theorem may seem rather abstract, but as we will see, it is a fantastic tool for computing the areas of arbitrary bounded regions. In particular, Green’s Theorem is a theoretical planimeter. WebTheorem 16.4.1 (Green's Theorem) If the vector field F = P, Q and the region D are sufficiently nice, and if C is the boundary of D ( C is a closed curve), then ∫∫ D ∂Q ∂x − ∂P ∂y dA = ∫CPdx + Qdy, provided the integration on the right is done counter-clockwise around C . . To indicate that an integral ∫C is being done over a ... WebThe proof of Green’s theorem has three phases: 1) proving that it applies to curves where the limits are from x = a to x = b, 2) proving it for curves bounded by y = c and y = d, and 3) accounting for curves made up of that meet these two forms. These are examples of the first two regions we need to account for when proving Green’s theorem. how to see building not flat in google maps
