补充资料:基本初等函数
基本初等函数包括以下6种:
(1)常值函数(也称常数函数) y =c(其中c 为常数)
(2)幂函数 y =x a(其中a 为实常数)
(3)指数函数 y =a x(a>0,a≠1)
(4)对数函数 y =logax(a>0,a≠1)
(5)三角函数:
正弦函数 y =sinx
余弦函数 y =cosx
正切函数 y =tanx(也记成y =tgx)
余切函数 y =cotx(也记成y =ctgx)
正割函数 y =secx
余割函数 y =cscx
(6)反三角函数:
反正弦函数 y =arcsinx
反余弦函数 y =arccosx
反正切函数 y =arctanx
反余切函数 y =arccotx
(反正割函数、反余割函数一般不用)
所谓初等函数就是由基本初等函数经过有些次的四则运算和复合而成的函数。
