The Precalculus textbook is a comprehensive book not intended to be completed in a single one or two-semester class. It contains twelve modules—approximately four modules per sixteen-week semester.

The following modules are generally used to cover the learning outcomes typical in Precalculus I:

• Module 1: Introduction to Functions
• Module 2: Linear Functions
• Module 3: Polynomial and Rational Functions
• Module 4: Exponential and Logarithmic Functions

The following modules are generally used to cover the learning outcomes typical in Precalculus II:

• Module 5: Systems of Equations and Inequalities
• Module 6: Sequences, Probability, and Counting Theory
• Module 7: Trigonometric Functions
• Module 8: Periodic Functions

The following modules are not cumulative and can therefore be used as additional content and rearranged as desired:

• Module 9: Trigonometric Identities and Equations
• Module 10: Further Applications of Trigonometry
• Module 11: Analytic Geometry
• Module 12: Introduction to Calculus
