摘要
对一类定积分的近似计算进行了研究,给出了2个积分不等式。以此,可近似估算出积分的值,并能确定其误差的大小。通过将积分区间细分,可进一步提高估算值的精确度,这为计算机编程提供了数学模型。
Studies the approximate computation of a definite integration and provides two new inequalities.This can approximately compute the value of integration and determine the integral error.By subdividing the integration interval,can improve the accuracy of computations further,and it provides mathematical models for computer programming.
