问题描述

我需要用Java开发一个程序来解决一些积分问题.像这样积分:

I need to develop a program in Java to solve some integrals. Integrals like this:

我已经在java.Math中寻找了一些函数来执行此操作，但是我什么都没找到.

I've looked for some functions to do this, in java.Math but I didn't find anything.

有人有想法解决这个问题吗? (也许有一些额外的库或类似的东西.)

Has anyone an idea to get a solution for this? (Maybe some extra libraries or something like that).

推荐答案

Wikipedia上有关数值积分的文章中有关于一维积分方法.

The Wikipedia article on Numerical Integration has a section on methods for one-dimensional integrals.

实现梯形"或矩形"规则应该没有问题.

You should have no problem implementing the "trapezoidal" or "rectangle" rule.
