Another reason I wanted to point this out in terms of the polar coordinates that we're using, is I think they're actually flipped from what you're used to seeing in physics.

另一个我想指出,我们采用极坐标的原因是，我认为它们实际上是,从你们习惯于看到的物理学中出来的。

I'll do so next time and probably in subsequent lectures because we're going to keep using these coordinates.

这点我们下几节课会讲到,下几节课我们会进一步阐述。

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

在薛定谔方程中，我们现在可以用,极坐标的方式来表示了。

OK, as I said, I want equality in the case of points to be, are the x- and y- coordinates the same?

好，正如我所说，我想要这个例子中的，点相等的意思是？

So, there is a way to go from the unprimed coordinates to the prime coordinate by rotating your axis and actually calculating the components.

现在我们有一种方法可以从原坐标系,转变到新坐标系,只要旋转坐标轴,并实际地计算一下坐标即可

There is the coordinates 8-201.

这就是8-201室的位置。

And similarly, actually, if we're looking at our polar coordinates here, what we see is it's any place where theta is equal to is what's going to put up on the x-y plane.

类似的，如果我们,看这里的极坐标系，我们能看到只要在theta等于,多少的地方就是ｘｙ平面。

I said both the x- and y- coordinates are bigger, then I'm going to return something to it.

我说过如果x和y坐标，都是更大的。

For the simplest context in which one can motivate a vector and also motivate the rules for dealing with vectors, is when you look at real space, the coordinates x and y.

对于最简单的情况,我们能用矢量,以及相关的规则来处理的,是实空间,x-y 坐标系
