函数是贯穿高中数学的一条主线,它的灵活应用可以解决很多问题.面对一道三角试题,我们从函数的角度来分析、探索,有时会利用函数的有关性质予以解决.方程思想也就是变量思想,从变量的角度来认识三角问题、分析三角问题.有时也会使问题顺利得到解决.一、应用函数单调性解三角问题函数单调性是求解大小关系问题的重要思路,很多与大小关系有关的问题,就是通过函数单调性解决的.
Function is a main line running through high school mathematics, its flexible application can solve many problems.Facing a triangle test, we analyze from the perspective of the function, exploration, and sometimes the use of the relevant properties of the function to be solved.Equation of thought is the idea of variables , From a variable point of view to understand the triangle problem, the analysis of the triangle problem.Often it will make the problem be solved smoothly.One, monotonicity of the application function Triangular problem function monotonicity is an important way to solve the problem of size, many related to the size The problem is solved by the monotonicity of the function.
