In physics and mathematics, Green's theorem combines line integrals on closed curves with? 6? 5C？ 6? What is 5 and the plane area? 6? 5D？ 6? Double integral of 5. Green's theorem is a two-dimensional special case of Stokes' theorem, named after the British mathematician george green. Let the closed region d be composed of piecewise smooth curves. 6? 5L？ 6? 5 in a circle, function? 6? 5P(x, y) and? 6? Where is 5Q(x, y)? 6? 5D？ 6? 5 has a first-order continuous partial derivative, then there is a positive boundary curve with L as d, and Green's formula can also be used to calculate the area of a plane figure. This formula is called Green's formula, which gives the relationship between the curve integral along the closed curve C and the double integral on the area D surrounded by C ...
