The (signed) area of a planar non-self-intersecting polygon with vertices (x_1,y_1), ..., (x_n,y_n) is A=1/2(|x_1 x_2; y_1 y_2|+|x_2 x_3; y_2 y_3|+...+|x_n x_1; y_n y_1|), (1) where |M| denotes a determinant. This formula is sometimes written ...
Area of a Convex PolygonThe coordinates (x1, y1), (x2, y2), (x3, y3), . . . , (xn, yn) of a convex polygon are arranged in the "determinant" below. The coordinates must be taken in counterclockwise order around the polygon, beginning and ending at the same point....
摘要: 110 8 2017-04-01 U nderstanding how one representation connects to another and how the essential ideas in that relationship are generalized can result in a mathematical theorem or a formula. In this article, we demonstrate this process by connecting a vector cross product in a...
