So, in a way, you can think of these as a space analog of polar coordinates because you just use distance to the origin, and then you have to use angles to determine in which direction you're going.
也可以把这种坐标,看成是空间中的极坐标,它其实使用了,距离原点的距离,然后用角度这种标尺,来确定了方向。
We also control where the graph appears by setting the origin using screen coordinates (see help coordinates for a discussion on the different kinds of coordinate systems).
我们还通过使用屏幕坐标(请参阅 help coordinates ,获得关于不同类型坐标系统的讨论)设置原点来控制曲线图显示的位置。
We could do it dy dx. Or, maybe we will want to actually make a change of variables to first shift this to the origin, x-2 you know, change x to x minus two and then switch to polar coordinates.
也可以dy,dx来划分,或者,对变量做一下变化,移动到原点,就是把x变成,然后再转化成极坐标。
