1.77245... I don't want to knowwhat the square root of pi is.
VOA: standard.other
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。
You know, if you're wandering through Harvard Square and you see an out-of-work Harvard grad, they're handing out examples of square roots, they'll give you an example and you can test it to see is the square root of 2, 1.41529 or whatever.
你知道,如果你从哈佛校园里穿过去,你看见了一个失业校友,正在派发平方根的示例,他们会给你一个例子,而你会检查2的平方根是1。41529或者别的什么。
Then if I'm looking for the square root of something less than 1, I know it will be in my region, right?
如果我要求平方根的数小于,我就知道我们的答案应该,在0-1这个区间了,对不对?
Let's call x the thing I'm trying to find the square root of. Let's start at 1. Square it.
让我们把求平方根的对象,这个数称为x,让我们从1开始。
If I say x is 2, I want to know, what's the square root of 2, well if you're enough of a geek, you'll say 1.41529 or whatever the heck it is, but in general, this doesn't help you find the square root.
如果我说X等于,我想知道,2的平方根是多少,那么如果你足够书呆子你就会说,1。41529或者随便什么玩意儿,但是大体上,它不会帮你算出平方根。
