函数e^x的性质及应用

The Nature and Applications of the Function e^x

在高等数学的学习中有一个应用起来很方便的函数就是e^x，这个函数有极为美好的性质，它是非负的，其导数和原函数都是自身，所以在数学证明中我们可以很方便的用它来构造函数、化简运算等。本文主要阐述e^x在应用方面的一些作用。

In the study of mathematics there is a function, e^x, which is very convenient in application. This function has a very beautiful nature,it is non -negative, Both the derivative and the original function are itself, so in mathematical proof we can easily use it to construct a function and so on. This paper concerns the nature and applications of the function e^x.
