例句

And a partial differential equation is some relation between its partial derivatives. Let me see.

而一个偏微分方程就是，函数各个偏导之间的联系，看看。

You don't need to bring a ruler to estimate partial derivatives the way that this problem asks you to.

你们不需要像这道题一样，用尺子去表示出偏导来。

A partial differential equation is an equation that involves the partial derivatives of a function.

偏微分方程就是，跟函数各个偏导数有关的方程。

So, we've learned about differentials and chain rules, which are a way of repackaging these partial derivatives.

我们还学过微分的链式法则，也就是用其他量来代替这些偏导数。

Well, hopefully you kind of vaguely remember that it was about functions of several variables and their partial derivatives.

希望你们大致记得，这是关于多元函数及其偏导的。

In particular, the directional derivatives in the direction of I hat or j hat are just the usual partial derivatives.

特别地，在i，j方向的方向导数是，一般的偏导数。

So the unknown is a function, and the equation will relate the partial derivatives of that function to each other.

未知量是一个函数，这个方程，将把函数的偏导数联系起来。

So, critical points, remember, are the points where all the partial derivatives are zero.

临界点是，偏导数都为零的点。

So, now, the next thing that we've learned about is partial derivatives.

然后是我们学过的偏导。

That's just the fact that the mixed second partial derivatives are equal.

这可以说明，二阶混合偏导数与次序无关。

And we have learned how to package partial derivatives into a vector, the gradient vector.

我们也知道了，如何将各个偏导组合成一个梯度向量。

That means it involves the first partial derivatives of whatever you put into it.

这意味着，不管放什么进去，都会包括一阶偏导。

So, we have to figure out what we mean by partial derivatives again.

因此，我们应该重新理解偏导数的含义。

Why do we like partial derivatives?

为什么我们偏爱偏微分呢？

These guys are functions so they count as numbers, but these are vectors and these are partial derivatives.

这些是函数，因此可以当作数来计算，但是这些是向量，这些是偏微分。

What we would start doing immediately is taking the partial derivatives. What is f sub x?

我们首先要做的事是，求偏导数，fx是多少？

Generally, you would want all the partial derivatives, 0 no matter how many variables you have, to be zero at the same time.

通常情况下，所有的偏导数—，无论有多少个自变量——都同时为。

And we have seen how to use the gradient vector or the partial derivatives to derive various things such as approximation formulas.

之后，又学会了怎样应用梯度向量和偏导，从而得到一些结论，例如函数的近似式。
