APPLICATION OF TANGENT EQUATIONS TO CREATIVE AND PROVE SOME INEQUALITIES

Abstract

In high school math program, inequality problems are difficult but rather common and are often taken in high school exams, university admissions, national math competitions, regional and international math Olympic competitions. Among several ways to solve these problems the tangential methodis far effective and often applied in many cases. In this paper, we recommend some ways to create exercises proving inequalities by using the tangent equations, help students find solutions as well as give some examples to practice. Based on the comments, students clarify the nature of some inequalities by using tangential methods.
