一代数推理题的特点代数推理是从问题出发借助规则进行的符号运算.二次函数、三次函数是高考数学中重点考查的内容(三次函数通过求导后转成考查二次函数),主要是与方程、不等式综合,考查数形结合,数式转换能力;数列是一类离散函数,考查应用能力,与不等式结合考查函数思想,逻辑 The characteristics of algebraic reasoning problems Algebraic reasoning is a symbolic operation proceeding from the problem with the help of rules. The quadratic function and the third-order function are the contents of the examination in the college entrance examination mathematics (the third function is converted into the examination of the quadratic function after derivation), mainly Integrate with equations and inequalities, examine the combination of number and form, and transform the ability of number conversion; series is a type of discrete function, examines application ability, and combines inequality with examination of function thought, logic
