### Overview

*Precalculus* is part of the acclaimed Art of Problem Solving curriculum designed to challenge
high-performing middle and high school students. *Precalculus* covers trigonometry, complex
numbers, vectors, and matrices. It includes nearly 1000 problems, ranging from routine exercises
to extremely challenging problems drawn from major mathematics competitions such as the
American Invitational Mathematics Exam and the USA Mathematical Olympiad.
Full, detailed solutions to all problems are built into the book.

As with all of the books in Art of Problem Solving's Introduction and Intermediate series, *Precalculus* is structured to inspire the reader to explore and develop new ideas. Each section starts with problems, so the student has a chance to solve them without help before proceeding. The text then includes solutions to these problems, through which new techniques are taught. Important facts and powerful problem solving approaches are highlighted throughout the text.
