Algebra and Trigonometry
Jay Abramson · OpenStax
Algebra is the study of mathematical symbols and the rules for manipulating these symbols. It is a unifying thread of almost all of mathematics. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Elementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values.

Design for Learning - Principles, Processes, and Praxis
Jason K. McDonald & Richard E. West · Brigham Young University
Our purpose in this book is twofold. First, we introduce the basic skill set and knowledge base used by practicing instructional designers. We do this through chapters contributed by experts in the field who have either academic, research-based backgrounds, or practical, on-the-job experience (or both). Our goal is that students in introductory instructional design courses will be able to use this book as a guide for completing a basic instructional design project.

Inequality and Interdependence
Kimberly Puttman, Kathryn Burrows, Patricia Halleran, Bethany Grace Howe, Nora Karena, Kelly Szott, and Avery Temple · LibreTexts
Inequality and Interdependence: Social Problems and Social Justice examines the persistent social problems of our world, asking both who suffers and who benefits. We explore inequality in issues that challenge communities today, such as education, mental health, death and dying, and disaster recovery, among others. We invite students to celebrate the work of those who remind us of our interdependence, to imagine powerful equitable solutions.

Proofs and Concepts - The Fundamentals of Abstract Mathematics
Dave Witte Morris & Joy Morris · University of Lethbridge
This textbook provides an introduction to proofs, logic, sets, functions, and other fundamental topics of abstract mathematics. It is designed to be the textbook for a bridge course that introduces undergraduates to abstract mathematics, but it is also suitable for independent study by undergraduates (or mathematically mature high-school students), or for use as a very inexpensive supplement to undergraduate courses in any field of abstract mathematics.

Introduction to Earth Science (C-ID: GEOL 121)
Timothy Ellsworth · Coalinga College
This is a general earth science texts that provides a broad understanding of the physical processes that have created and regulate space and Earth’s four spheres: the hydrosphere, biosphere, atmosphere, and geosphere. The course integrates the physical sciences to provide an interdisciplinary, spatial and temporal perspective of the connections and interactions between these spheres. The course is designed to serve as a textbook for C-ID GEOL 121.

Waves: An Interactive Tutorial
Kyle Forinash and Wolfgang Christian · LibreTexts
This is a set of interactive tutorials designed to teach the fundamentals of wave dynamics. It starts with very simple wave properties and ends with an examination of nonlinear wave behavior. The emphasis here is on the properties of waves which are difficult to illustrate in a static textbook figure. The tutorial may be used in conjunction with a text or as a stand alone introduction to waves. Exposure to calculus and basic physics is assumed in the latter sections.
