When we look at this angular part, we see that it's always the square root of 1 over 4 pi, it doesn't matter what the angle is, it's not dependent on the angle.
当我们看这角向部分,可以看到它总是等于1除以4pai开根号,这和是什么角度没有关系,它和角度无关。
So I guess I should go back, and let me do this correctly this way. Again, I can look at test, test and I guess test now if I want to get the element out-- angle bracket or square bracket?
但是这不是我想要的对不对?,我认为我该回到这里,让我改正这个错误,好,那么我还是对元组,那么现在我想从test中取出元素来?
