指数函数是数学知识中的重要内容之一,学生学习这个内容时感到很困难,主要是没有对指数函数加以严格定义,学好了指数函数,也学好了它的反函数—对数函数。因此本文就从中学对指数函数的描述;用幂级数定义指数函数;指数函数的简单应用等方面论述这个题目,这对在教学中解决教学难度,提高教学质量等都具有十分重要的意义。
Exponential function is one of the important contents in mathematics knowledge. It is difficult for students to learn this content. The exponential function is not strictly defined, the exponential function is well learned, and the inverse function - logarithm function is also learned. Therefore, this article from the middle of the description of the exponential function; the exponential function defined by the power series; exponential function of the simple application discusses the subject, which is difficult to solve in teaching teaching, improve teaching quality are of great significance.
