These methods are improper to be used in this thesis except the finite difference method , finite integral method 这五种方法中除有限差分法和有限积分法较为适用本文计算需要外,其它几种方法都存在诸多弊端,不宜选用。
A finite difference is a mathematical expression of the form f(x?+?b) ? f(x?+?a). If a finite difference is divided by b???a, one gets a difference quotient.
