THE METHOD PROVING INEQUALITY BY USING TANGENTIAL CURVE

Abstract

Inequality and related problems is a growing problem that attracts the attention of many people studying primary mathematic. Inequality issues occupy an important position in elementary math and are used a lot in national and international exams for excellent students. We know there are many techniques and methods to prove the inequality. With the aim of developing methods and techniques to prove the inequality. In this paper, using the extended Jensen inequality, we
develop the tangent method into the tangent curve method to prove some inequality problems under non-linear conditions.
