一般地,对于多元三角方程,其解是不能完全确定的。正是源于此,许多同学对解多元三角方程深感无从下手。事实上,只要我们把握住它的特征,采用一定的方法,是可以找到解题途径的,并且预见到解题的进程。本文试图从多种角度给出解这类方程的方法,供同行们教学时参考。一、利用非负数的性质就是设法通过配方, In general, for a multivariate trigonometric equation, its solution cannot be completely determined. It is precisely because of this that many students have no idea what to do when solving a multivariate equation. In fact, as long as we take hold of its characteristics and adopt certain methods, we can find ways to solve problems and foresee the process of solving problems. This article attempts to give a solution to this type of equation from various perspectives for reference by colleagues. First, the nature of using non-negative numbers is to try to pass the formula,
