With the reform of secondary school mathematics, teaching gradually emphasizes tracing the nature of the problem. Conditional extreme value is one of the knowledge points that bridges higher mathematics and elementary mathematics. This paper adheres to the idea of the high point of view, connects the conditional extreme value in higher mathematics with the most value problem taught in secondary school, and uses Lagrange number multiplication to solve the distance, area extreme value problem. Conic curve as an example, the high point of view of the background of the conditional extreme value solution and high school commonly used to solve the inequality problem ideas. By solving the partial derivatives listed in the system of equations to determine the coordinates of the point, the practice is simple, novel ideas, easy to operate. It is conducive to students' expansion of ideas and enhancement of disciplinary literacy.
