Notice it's no longer even a function of theta.
注意，它不再是,关于θ的函数。
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.
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
Say, polar coordinates. Let's say that I have a function but is defined in terms of the polar coordinate variables on theta.
比如说极坐标，有一个函数,是根据极坐标θ定义的。
So we have the operationon the wave function in terms of r, theta, and phi and remember this e is just our binding energy for the electron, and we get back out this wave function.
我们用r，θ，φ来表示,将算符作用于波函数,而且记住e仅仅是电子结合能，然后后面加上波函数。
The velocity of that object as a function of theta is given Rd And I can make you see that very easily.
物体的速度,和θ的关系是,θ/dt，by，R，d，theta/dt。,我可让你们简单得看。
That's exactly right, y0 because then the distance R between here and the y zero is R, so this is the potential energy as a function of angle theta.
它非常正确，因为这样，这里和,的距离是，因此这是势能,关于θ的变化。
That's exactly right, y0 because then the distance R between here and the y zero is R, so this is the potential energy as a function of angle theta.
它非常正确，因为这样，这里和,的距离是，因此这是势能,关于θ的变化。
