The problem of the maximum value is a common and important problem type in analytical geometry. Its solution involves functions, inequalities, trigonometric functions, plane geometry knowledge and other important content. The most value problem also involves many important mathematical thinking methods. The method to solve the most value problem is helpful to train students’ ability of comprehensive analysis and problem solving. This article introduces several common methods to solve problems by using examples. First, use the definition of conic curve The definition of conic curve is to solve the problem of analytical geometry. can
