化归思想是数学学科中的重要素养组成部分,也是数学中非常重要的一个突破难点,实际上,在数学学习的过程中,化归思想就是将未知化为已知,将繁杂的化为简单的,将难以理解的化为简单的,如将分式方程化为整式方程,将四边形问题转化为三角形问题,将代数的问题化为几何的问题等。实现这种化归思想的转化的方法有很多种,要学好化归思想,学会如何应用化归思想是非常重要的,尤其在三角函数的问题上,下面笔者就浅谈有关化归思想在解三角函数问题中的应用。
The thought of returning to normalization is an integral part of maths discipline and also a very important breakthrough in mathematics. In fact, in the course of maths learning, the idea of returning to the past is to change the unknown into the known and the complicated into the simple , Will be difficult to understand into a simple, such as the fractional equation into an integral equation, the quadrilateral problem into a triangle problem, the algebra problem into a geometric problem. There are many ways to realize the transformation of this idea into the thought, it is very important to learn how to apply it to the thought, and learn how to apply it to the thought. Especially in the question of the trigonometric function, Application of trigonometric function problem.
