another function G of the end minus the start,

与起点值的差
with G as that function whose derivative is F."

其中函数 F 是函数 G 的导数"
Maybe there is going to be some other magic function

也许在二维空间有个神奇的
U in two dimensions related to F, in some way,

关于 F 的函数 U
so that this integral is again given

使得这个积分值
by a difference of something there minus something here.

等于那里减这里的差
If that is the case, then you can rearrange it and get this.

如果是这样重新整理一下等式就好了
But you will find that it's not meant to be that simple.

但你会发现这没有那么简单
So, again, has anybody heard rumors

你们有没有人听过
about why it may not be that simple?

为什么它没那么简单
What could go wrong? Okay so, yes?

错误会出现在哪里好吧请说
Okay, that's probably correct

好的也许是对的
