引参消参法是数学中一种重要的解题方法.它能解决数学各科中的最值问题.现仅就它在求三角函数最值问题方面的应用简介如下:所谓引参消参法,就是根据题给的条件,引进参数(引参),但是不必求出其参数值.再根据已知条件和所学过的知识,将其参数消去 The introduction of reference parameters is an important method in mathematics problem solving method that can solve the problem of mathematics in the most value. Now it is only in seeking the most value of the trigonometric function of the application profile is as follows: Law, is based on the conditions given to the introduction of parameters (cited reference), but do not have to find its parameter values.According to known conditions and learned knowledge, its parameters eliminated
