摘要
通过建立与高阶可微函数有关的恒等式,证明了有关文献给出的关于定积分的一个上界,并给出误差估计,最后给出对带有权函数的定积分的一个上界.
Some integral identities involving higher order differentiable functions are established. A new proof of an upper bound on definite integral is given by the identity. Error estimations and an upper bound on definite integral with weighted function also are given.
