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。
