5) even and odd functions
偶与奇函数
6) multiple odd and even function
多元奇偶函数
1.
This paper presents the concept of multiple odd and even function,and develops the property of fixed integral of odd and even function in a symmetrical space into the integral of multiple odd and even function in a symmetrical space by means of difinition of the odd and even property of function F(x)=f(x,y)dy in the space [a, -a],so the calculation of this sort of integration is simplified.
给出了多元奇偶函数的概念,并将在对称区间上奇偶函数的定积分的性质,通过定义在区间[a,-a]上的函数F(x)=(x)f(x,y)dy的奇偶性,推广到多元奇偶函数在对称区域上的积分中,从而简化了此类积分的计算方法。
