在转换文档时，XSLT是一种极其高效的语言，但对于更为传统的任务，比如说在求微分方程的积分或与数据库通信时。

XSLT is a wonderfully efficient language for transforming documents, but it's not always the best language for more traditional tasks like integrating differential equations or talking to databases.

We want to integrate. So let's take the integral of both sides, going from the initial point to the final point.

分别从初态,到末态做积分，消去微分。

In other words, your job is to guess a function whose second derivative is a, and this is called integration, which is the opposite of differentiation, and integration is just guessing.

换言之,你的任务是要猜出一个二阶导数为a的函数,这就是积分,和微分恰恰相反,积分就是猜
