So using theory of power series to define and study function is an effective method of deal with question of function.

因此，用幂级数定义和研究函数是处理函数问题的一种有效的手段，并能给问题的解决带来一些方便，但是，幂级数只是函数的一种表示形式，只有与函数的其他表示形式相互协调和补充，才能真正简洁有效地处理函数问题。

There is evidence about the knowledge of the Summation Series, ever since the Pyramid Temple of Khafra, at Giza, built in 2500 BCE, i.e.
