OK. Now, having done that, again I want to stress this idea and I'm going to write it out one more time, that there's a particular format here.
好,讲完了这些,我又想要强调一下这个思想,并且再一次把它写出来了,就是有一个特定的格式。
Then we go negative and we go through zero again, which correlates to the second area of zero, that shows up also in our probability density plot, and then we're positive again 0 and approach zero as we go to infinity for r.
并且再次经过,这和,第二块等于0的区域相关联,这也在,我们的概率密度图里反映出来了,然后它又成了正的,并且当r趋于无穷时它趋于。
