Abstract Inequality is the basic content of mathematics. At the same time, the maximum value problem is a hot test point in inequality problems. It can be closely combined with functions, images, analytic geometry and other knowledge. It makes the problem more complicated and becomes a major difficulty for most beginners. Taking specific topics as examples, this paper explores a mode solution method for inequality problems, and summarizes it. This paper concludes the inequality problems based on conic curve, vector and function, comments and summarizes each problem, so that readers can establish basic inequality thinking.
