How to solve inequalities. Chris Tisdell UNSW Sydney

I present a simple example of how to solve a basic inequality arising in calculus and the theory of functions. Such ideas are seen in first-year university or high school mathematics.

Inequalities are used in virtually all areas of mathematics and its applications. A good understanding of inequality techniques empower us to solve more difficult problems where inequalities arise (eg: in optimization; in linear programming; in error bounds for numerical approximation etc).
