Analyze the changing process in practical problems;
(2) Find and ask questions:
Precipitation constants, variables and their relationships; ?
(3) Collecting and analyzing data:
Make clear the basic characteristics of its movement change, so as to determine its movement change type; ?
(4) Select the function model:
According to the analysis results, the appropriate function type is selected to establish a mathematical model, and the actual problem is reduced to a mathematical problem; ?
(5) Solving the function model:
According to practical problems, the functional model is solved by operational reasoning; ? For example, calculate the special value of the function, and study the monotonicity, maximum value, maximum value and minimum value of the function.
(6) Test model:
The solution of function model is used to explain the changing law of actual problems and achieve the purpose of solving problems.
