Integration by substitution 中文
Nettet"Integration by Substitution" (also called "u-Substitution" or "The Reverse Chain Rule") is a method to find an integral, but only when it can be set up in a special way. The first and most vital step is to be able to write our integral in this form: Note that we have … Nettet"换元积分法" 是求积分的方法，适用于可以写成一个特定格式的函数。 第一步，也是最重要的一步，是把积分写成这个格式： 注意积分里有 g(x) 和它的 导数 g'(x) . 像这例子： …

NettetOne of the most important rules for finding the integral of a functions is integration by substitution, also called U-substitution. In fact, this is the inverse of the chain rule in differential calculus. To use integration by substitution, we need a function that follows, or can be transformed to, this specific form: NettetIntegration by substitution can be derived from the fundamental theorem of calculus as follows. Let ƒand φbe two functions satisfying the above hypothesis that ƒis continuous …
NettetIn this explainer, we will learn how to use integration by substitution for definite integrals. Let us first recall how to integrate by substitution by going through a quick example. Let 𝐼 = 𝑥 2 𝑥 + 5 𝑥. d. We compute this integral by making the substitution 𝑢 = 2 𝑥 + 5 . We have that d d 𝑢 𝑥 = 6 𝑥, and so 𝐼 = 1 6 ...
