Method to prove inequality
*******
¡¾Abstract¡¿That inequalities in mathematics was very important role and status
and is evaluated, reasoning, mathematical way of thinking is important to infiltrate into the subject is math content of the important component of the inequalities in the process needs to be used in many mathematical thought, with many important mathematical content¡£In this paper, I summarized some mathematical inequality proof methods. Inequality in elementary mathematical proof commonly use in comparative law, for commercial, analysis, synthesis, mathematical induction, the reduce- tion to absurdity, discriminant, function, Geometry, and so on. Inequality in higher mathematics proof often use the intermediate value theorem, Taylor formula, the Lagranga function and some famous inequality, such as : mean inequality, Kensen inequality, Johnson in- equality, Helder inequality, and so on. Inequality proof methods get more efficient and help us further explore and study the inequality proof. Through the study of these proof methods, we can solve some practical problems, develop logical reasoning ability and demonstrated the ability to abstract thinking and grow hard thinking and good at thinking of the good study habit¡£
