Trigonometry: A Combination of Algebra and GeometryPaperback, 20 December 2020

Trigonometry is a book that covers most of the fundamental concepts taught in a Precalculus course. I walk the reader through these ideas conceptually, that the ideas might come to life. Think of this book as a tutor guiding you through the math, gently leading you to not only do the math, but to fully understand it.
