| Abstract |
Derivative is an important content of senior high school mathematics, which can solve many function problems, and it often appears as the finale in college entrance examination mathematics. Among them, finding the range of parameters in the problem of constant inequality with parameters is one of its popular questions, which are generally difficult, involve comprehensive and complex knowledge points and require high students mathematical literacy. This paper sorts out the college entrance examination questions and simulation questions in recent years, and summarizes four commonly used methods to solve such problems. I hope this article can.
