We are finding a parametric equation for the sphere using two variables phi and theta which happen to be part of the spherical coordinate system.
我们建立有两个变量φ和θ的球面的参数方程,它们恰好是,球坐标系统的一部分。
This is called a "right-handed" coordinate system because the thumb and first two fingers of your right hand can be used to represent the three directions.
这被称为“右手”坐标系统，因为你右手的大拇指、食指和中指可以被用来表示三个方向。
