代数应用类问题,最主要的特点就是:由实际情景(非数学)抽象概括成数学问题,进而解决数学问题,使原问题获解,其中“由非数学到数学”就是将实际问题化归到对应的数学模型,常见的类型根据实际问题所包含的关系及其所列式的特点可分为:(一)方程或不等式(包括一元一次方程、二元一次方程及方程组、一元二次方程、分式方程、一元一次不等式及不等式组)(二)函数与不等式结合(三)二次函数型
Algebraic application of the problem, the most important feature is: abstracted from the actual situation (non-mathematical) abstract into mathematical problems, and then solve mathematical problems, so that the original problem is solved, in which “from non-mathematical to mathematical ” is the actual problem According to the actual problems contained in the relationship and the characteristics of its type can be divided into: (a) equation or inequality (including a linear equation, a bivariate equations and equations, a binary Sub-equation, fractional equation, a unitary inequality and inequality group) (two) combination of function and inequality (three) quadratic function type
