微分在数学中的定义:由函数B=f(A),得到A、B两个数集,在A中当dx靠近自己时,函数在dx处的极限叫作函数在dx处的微分,微分的中心思想是无穷分割。微分是函数改变量的线性主要部分。微积分的基本概念之一。

This should be particularly bothersome to you because, as you've already experienced in 5.60, There are a lot of partial derivatives.
对你们来说这可能很让人头疼,就像你们在5。60里体验过的那样,这有很多偏微分和变量。
We want to integrate. So let's take the integral of both sides, going from the initial point to the final point.
