现在需要计算一个以a，b为半轴的椭圆的面积,其实椭圆就是一个被压扁的圆。

Let's say that we want to find the area of an ellipse with semi-axes a and b. OK, so that means an ellipse is just like a squished circle.

你们都知道，要求这个面积是非常简单的，如果你们想的话，可以积分除了椭圆函数以外的任何函数。

So, you know, if you find that the area is too easy, you can integrate any function other than ellipse, if you prefer.

结果，这导致了比起运行到远地点(椭圆形月球轨道的最远端)时的满月，那天的月亮面积增大14%，亮度增加30%。

As a result it appeared some 14 percent larger and 30 percent brighter than a Full Moon near apogee, the most distant point in the elliptical lunar orbit.
