The subject of mathematical inequalities is tied closely with optimization methods. While most of the subject of inequalities is often left out of the ordinary educational track, they are common in mathematics Olympiads.
Contents
Motivation
We say that a>b (or, equivalently, b<a) if a and b are real numbers, and a-b is a positive number. However, there are many inequalities thare are much more interesting and also very important, such as the ones listed below.
Famous inequalities
Here are some of the more famous and useful inequalities, as well as general inequalities topics.
- Arithmetic Mean-Geometric Mean Inequality
- Cauchy-Schwarz Inequality
- Chebyshev's Inequality
- Geometric inequalities
- Holder's Inequality
- Isoperimetric inequalities
- Jensen's Inequality
- Minkowski Inequality
- Power mean inequality
- Rearrangement Inequality
- Schur's Inequality
- Triangle Inequality
- Trigonometric inequalities
- Trivial inequality
Problem solving tactics
substitution, telescoping, induction, etc. (write me please!)
