--description--

椭圆的定义是：给定一个圆心c，其中心为M，半径为r，点G为d（G，M）

椭圆点的构造如下所示。

给定的是M（-2000,1500）和G（8000,1500）。给定也是具有中心M和半径15000的圆c。与G和c等距的点的轨迹形成椭圆e。从外部的点P开始，绘制两个切线t1和t2到椭圆。让t1和t2接触椭圆的点为R和S.

对于多少格点P，角度RPS是否大于45度？

--hints--

euler246()应该返回810834388。

assert.strictEqual(euler246(), 810834388);

--seed--

--seed-contents--

function euler246() {

  return true;
}

euler246();
