Let's plot droplet velocity as a function of looking at the number that have this velocity 0 with the zero being in the center here.

我们将液滴的速度设定为,观察那些数字作用，在中心的地方,速度为。

The other obvious one to do would be worst case. Again, over all possible inputs to this function, what's the most number of steps it takes to do the computation?

很明显另一种就是针对最坏的情况了,也就是在所有可能的输入,里面选出用的,步骤最多的那个输入？

It's just reminiscent of a previous program 9 9 9 or a previous function the number 9, 9, 9 so what does that really mean?

它提醒之前的程序,或者之前的函数，那个数字，那其实表示的是什么呢？

Normally, I will give you a function and tell you to take any number of derivatives.

通常情况下,我会给你一个函数,然后让你求任意阶的导数

So, it turns out that n is not the only quantum number needed to describe a wave function, however. There's two more you can see come out of it.

事实上，n不是描述一个波函数需要的,唯一的量子数，你们可以看到，还需要，两个量子数。

As I said, what we want to do is, we want to count the number of basic steps it takes to compute a computation as a function of input size.

我刚才提到了，我们要建立，一个根据输入大小的方法来计算,一个计算过程需要的时间,建立这个方法需要几步呢？

Of course, you can take a function and take derivatives any number of times.

当然,你可以随意拿一个函数,对它求任意阶的导数

I would say, okay, this guy wants me to find a function which reduces to the number a when I take two derivatives, and I know somewhere here, this result, which says that when I take a derivative, I lose a power of t.

出题者想要我找出一个函数,它在经过两次求导后得到数字a,我知道这里的某个地方,这个结论告诉我,我每求一次导,t就降一次幂
