摘要:方程是表示两个数学式(如两个数、函数、量、运算)之间相等关系并含有未知数的一种等式,通常在两者之间有一等号“=”。方程不用按逆向思维思考,可直接列出等式并含有未知数,它广泛应用于数学、物理等理科应用题的运算。文章主要初步分析线性方程组中的方程问题,奥数中出现的方程问题,常微分方程中的问题并举了一些简单例题。

Abstract:Equation is said two mathematical type (e.g., two Numbers, function, quantity, operation), an equation of the equal relationship between between the two usually have a equal sign "=". Equations need not press the reverse thinking thinking, can be directly listed equations and variables, it is widely used in mathematics and physical science application operation. Problem of equation in this paper preliminary analysis system of linear equations, equations in mathematical olympiad problems, problems in ordinary differential equations and some simple examples.
Keywords: Equation of the problem; The linear equation; Mathematical olympiad; Ordinary differential equations
