也就是，这里是它的极坐标表示法，一些有意义的随机数字集。

Here's the polar representation of it, some random set of Numbers which makes sense.

反过来，有一个关于x和y的函数,也可以表示成极坐标r和θ

Or, the other way around, I have a function of x and y and I want to express it in terms of the polar coordinates r and theta.

本文讨论了参数方程和极坐标方程表示的曲线的对称性，给出了判定这两种曲线的对称性的充分条件。

In this paper, the symmetry of curved lined given by parametric equation and polar coordinates equation is discussed and the sufficient conditions are given.

在薛定谔方程中，我们现在可以用，极坐标的方式来表示了。

In terms of the Schrodinger equation, we now can write it in terms of our polar coordinates here.
