用工程数学知识求广义实积分的值

Solving generalized real integral problems using engineering mathematics

合理而恰当地运用工程数学知识可以更快更好地求得高等数学中一些不好求的广义实积分的值。利用傅立叶变换和拉普拉斯变换以及复变函数中的残数等多种工程数学知识求广义实积分的值,表明工程数学的知识使我们有更多的方法去处理和解决数学问题。

By reasonable and appropriate use of engineering mathematics, one can solve some difficult real integral problems in higher mathematics easily and fast. In this paper,tools in engineering mathematics such as Fourior Transform , LaPlace Transform and residues in complex functions are used to find the values of generalized real integrals. The paper shows that engineering mathematics provides us with alternatives to deal with and to solve mathematics problems.
