奇函數(shù)加奇函數(shù)是什么函數(shù)
2021-03-21 14:45:27文/李文源奇函數(shù)加減奇函數(shù)是奇函數(shù)，偶函數(shù)加減偶函數(shù)是偶函數(shù)，奇函數(shù)乘奇函數(shù)是偶函數(shù)，偶函數(shù)乘偶函數(shù)是偶函數(shù)，奇函數(shù)乘偶函數(shù)是奇函數(shù)。
奇函數(shù)加奇函數(shù)是什么函數(shù)
奇函數(shù)±奇函數(shù)=奇函數(shù)
偶函數(shù)±偶函數(shù)=偶函數(shù)
奇函數(shù)×奇函數(shù)=偶函數(shù)
偶函數(shù)×偶函數(shù)=偶函數(shù)
奇函數(shù)×偶函數(shù)=奇函數(shù)

奇函數(shù)：如果對(duì)于函數(shù)f(x)的定義域內(nèi)任意一個(gè)x，都有f(-x)=-f(x)，那么函數(shù)f(x)就叫做奇函數(shù)。
偶函數(shù)：如果對(duì)于函數(shù)f(x)的定義域內(nèi)任意一個(gè)x，都有f(-x)=f(x)，那么函數(shù)f(x)就叫做偶函數(shù)。
