THE LEVEL-SET METHOD COMBINED WITH DESMOS SOFTWARE TO ORIENT THE SOLUTION OF INEQUALITY PROBLEMS

Abstract

 In this paper, we present the level-set method combined with Desmos software - a free graphing and teaching tool to analyze and find elementary solutions for inequality problems in high schools. Besides, we also show that Desmos outperforms some previous methods in predicting solutions to inequality problems. Moreover, the description of the optimization problem through visual images will help users feel better about the relationship between the optimal solution to optimization problems with feasible solutions; thereby better understanding the optimization problem in general as well as the inequality problem in particular.
