对于两个实数a和b,若a＞b，则可令a=b+t，其中t＞0称为增量。通过设置增量元素，利用增量代换来解答和处理问题的方法叫做增量方法。本文从增量方法的解题功能入手，介绍其在求解数学问题时的几种常见的巧妙运用，供大家参考．一、巧借增量设元，摆脱根号纠缠．某些无理方程或?
For two real numbers a and b, if a>b, then a=b+t can be made, where t>0 is called increment. By setting incremental elements, the method of solving and solving the problem by incremental substitution is called incremental method. This paper starts with the problem-solving function of the incremental method and introduces several common and clever applications for solving mathematical problems for your reference. One, clever use of incremental design elements, get rid of root entanglement. Some irrational equations or?
