I. Overview The main content of this lesson is to learn the most value problem in conic section. It is the process of further exploring the conic curve after learning the three kinds of conic curve standard equations and geometric properties, curves and equations, reflecting the conic curve. The essential features of the curve reveal the existence conditions of the curve and the geometric properties it contains. It is an extremely important content. Second, the analysis of teaching objectives (a) knowledge and skills: to enable students to clearly seek the basic method of the value of the conic curve; (b) the process and methods: to develop students’ ability to analyze problems and solve problems, penetrate the number of forms of integration, The thought of conversion and transformation;
