This text focuses on understanding concepts rather than on presenting rote procedures, and blends the various topics and applications of contemporary precalculus. Graphical, algebraic and numeric perspectives are provided, offering a broad view of topics.

With an emphasis on techniques, this volume focuses on the applications of basic mathematics and differential and integral calculus in the field of business, economics and the life and social sciences. All mathematical theorems, proofs and concepts are described intuitively and then mathematically. Reorganized and rewritten material includes chapters on exponentials and logarithms, curve sketching and optimization, application sections of straight lines and quadratic inequalities. A new section on difference equations and expanded coverage of differential equations is included.

This work develops the trigonometric functions using a unit circle approach and shows how it leads to the right triangle approach. Graphing techniques are emphasized, including a discussion of polar co-ordinates, parametric equations, and conics using polar co-ordinates.

It is a different book to others because it contains learning methods of integral calculus and proves to be useful for students and teachers of High Schools, Colleges Bachelors, Universities and Technological Institutions.

Allowing students to focus on real-life applications of mathematics. Selected examples feature traditional algebraic as well as optional graphing calculator solutions. We have taken great care to only use this format in examples where the graphing calculator can naturally be used to support and/or enhance the algebraic solution. For those interested in Mathematics.
