Programming Precalculus with Python is designed to help students learn the fundamentals of Python programming and the basics of precalculus within the context of Python programming. The book presents the basic elements of the language, including control structures, list and set operations, built-in math functions, user-defined functions, string manipulations, logical structures, list comprehension, classes, and 2D and 3D plotting. Opening chapters cover sequences and series, counting and probability, and operations on polynomials. Students learn about systems of equations and matrices, number theory and logic, coordinate geometry, graph features, complex numbers, the fundamental theorem of algebra, and rational functions. Closing chapters focus on exponential and inverse functions, as well as logarithms. Each chapter includes exercises in both precalculus and programming, as well as independent programming projects from diverse fields of mathematics. Sample programs included throughout the book are written in such a way that they are easy for a fledgling programmer to follow and understand. Providing students with a comprehensive and approachable guide, Programming Precalculus with Python is an ideal resource for Precalculus I and Python programming courses within mathematics departments and programs.
