前言
脑补知识点:
1.向量的内积(数量积,点乘):
公式:a· b = |a| * |b| cos=a.x* b.y + b.x * a.y
2.向量的外积(向量积,差乘):
公式:|c|= |a|*|b|*sin = a.x * b.y - b.x * a.y
点在多边形内判定
多边形: 就是二维平面上被一系列首尾相接、闭合的折线段围成的区域 在程序中一般用定点...

Math.sin(x) x 的正玄值。返回值在 -1.0 到 1.0 之间;Math.cos(x)x 的余弦值。返回的是 -1.0 到 1.0 之间的数;这两个函数中的X 都是指的“弧度”而非“角度”,弧度的计算公式为: 2*PI/360*角度;30° 角度 的弧度 = 2*PI/360*30如何得...
