数学思想方法是数学的灵魂,是解决数学问题的金钥匙,灵活运用各种数学思想方法是提高解题能力的根本所在.下面举例说明几种常见的数学思想及其应用.一、方程思想利用未知数表示有关的量,列出式子,进而列出方程,然后通过解方程求出问题的解的数学思想就是方程思想.本章在研究余角、补角的有关计算时就通常设未知数列方程,用代数方法解答.
Mathematical thinking method is the soul of mathematics, is the golden key to solve mathematical problems, the flexibility to use a variety of mathematical thinking is the fundamental solution to improve the ability to solve the following examples illustrate several common mathematical ideas and their applications. The unknowns represent the relevant quantities, list the equations, and then list the equations, and then solve the equation to find the mathematical solution of the problem is the idea of equations .This chapter in the study of extra-angle, supplementary angle calculation is usually based on unknown equations , Using algebraic methods to answer.
