The first person let me go ahead and check out before him because of (x); other people did the same thing because of f(x). The essence of (x) is unknown.
第一个让我先结账的人是因为（x），而其他人这么做是因为（x），而这个x却是未知的。
Well, we have seen that it is given by the partial derivative f sub x.
我们已经发现,它由f对x的偏导数给出。
Why is that? Well, let's say that f sub x is zero.
为什么呢？我们令fx为。
What I'm integrating to is f of x of t and y of t.
我积分的是f，y
x And then, I can write partial f over partial x.
接着，我可以写出∂f/∂
