getTriangularHeight2 static method

double getTriangularHeight2(
  1. double hypotenuse,
  2. double angle
)

传入直角三角形斜边和其中一个夹角，然后计算斜边为底的高度h

Implementation

static double getTriangularHeight2(double hypotenuse, double angle) {
  //另外两条边
  final section = angle2SinSlope(angle) * hypotenuse;
  final section2 = angle2CosSlope(angle) * hypotenuse;
  final h = section * section2 / hypotenuse;
  return h;
}
