我已经有了一些笛卡尔坐标点了,我可以创建一个极坐标点。
然后给它们赋值半径和角度,然后我可以进行刚才的操作,也就是说,对刚才的笛卡尔坐标进行的操作,让我们来运行下它吧,运行下,现在我有一个极坐标点。
And then I could do things like again, say, okay having done, that let me just run it here, run that, so I've now got polar point 1, and polar point 2.
If I want to get out right now the versions of these things, I can ask what's the value of c p 1 x, and it returns it back out.
你可以在那里看到那些,代表笛卡尔坐标点的东西,如果我想要得到现在,这个类的版本的东西的话。
I've got Cartesian points, I could create a polar points.
