摘要
在一定的条件下给出了两个含参数的积分不等式,其误差估计是最佳的。由此统一处理了积分近似计算的中点矩形法、梯形法和抛物线法中出现的三个基本的不等式。
Two integral inequalities with a parameter whose estimation of errors is best were given under certain conditions.Thus an unified treatment of three fundamental inequalities in midpoint-rectangular rule,trapezoidal rule and parabolic rule for calculating definite integrals approximately was provided.
