I like that answer. I then tested it on the square root of 9, and as I mentioned last time, I didn't find 3. I was not crushed.
我喜欢这个答案,然后我又试了试9的平方根，跟我上次说的一样，答案不是3。

All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.
好，我试试求2的平方根,我当然不希望得到一个完全准确的答案了,但是我得到了一个近似值，试试将这个数平方一下,你会发现结果和2相当接近。

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。

I think you can tell by analogy with what I did in one dimension that the position of that object at any time t is going to be the initial position plus velocity times t plus one half a t square.
你们可以类比一下我在一维情况下的结论,这个物体在任意时刻 t 的位移,等于初始位移,加上 v ? t + 1/2 ? a ? t^2

I'm checking that I didn't leave my program because I didn't find an answer. Well this is a good thing, it's better than my program running forever, but it's a bad thing because I don't have it the square root of 0.25.
我对计数器要做个验证,因为我不会没得到答案就退出程序,好，这其实是个好事,因为它不会让我的程序永远跑下去，但这也是件坏事因为,我没得到0。25的平方根。

It doesn't help you find square roots.
它不会帮你算出平方根。

And the good news was we didn't have to worry about how math did square root or anything like that, we just got it and we used it.
也可能是其他数，好消息是,我们不必担心math函数是怎样开方的,我们只要使用它就好。

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。

Now, I hope you guys know that much calculus, that when you take a derivative of a function of a function, namely v square over 2 is a function of v, and v itself is a function of t, then the rule for taking the derivative is first take the v derivative of this object, then take the d by dt of t, which is this one.
我希望你们了解更多的微积分知识,当你对复合函数求导时,也就是说v^/2是关于v的函数,而v本身是关于t的函数,求导的法则应该是,第一步是这一部分对v求导,然后v再对t求导,得到这一部分
