定积分的两个特殊性质在三角积分中的应用

An application of two special qualities about definite integral on trigonometric integration

在这篇论文中,我们提出定积分的两个基本性质,这些性质很容易证明,在求某 些复杂积分时,这些性质非常有用.

In this paper, two basic qualities about definite integral are proved. The proof procedure of these qualities is simple, and these qualities are very useful in calculating some complex integrators.
