摘要
利用奇函数和偶函数的积分性质,以及泰勒公式,对于定义在区间[a,b]上的函数f(x)的积分I=∫abf(x)dx,给出了一个更高精度的数值积分公式,推广和改进了文献[1]中已有的结论.
In this paper, by using integration property of odd function and even function and Taylorformula, we obtain a more pref else formula of a numerical - integration for the integration I =a^bf（x）dx of function for defined interval [a, b] and the conclusion of the existed documents has been improved and extended.
