Precalculus thoroughly explores topics in algebra, trigonometry, and analytic geometry, and all the examples, applications, and exercises have been selected for their relevance to calculus. The trigonometric functions are introduced first in terms of the unit circle approach and then using right triangles. The text includes over 6,000 exercises that accommodate a variety of teaching and learning styles, plus a number of contemporary, real-life applications.

This book contains 712 solved problems, with step-by-step solutions, concepts and proofs in plane geometry, trigonometry, and solid geometry, sample problems and help dealing with such complexities as trapezoids, regular polygons, methods of proof, and more.

SparkNotes Math Study Guides cover a wide range of math topics, detail steps for solving problems and equations, and include practice problems.
