On this page you will find several open Mathematics textbooks along with supplemental material and a few lecture videos.  

The purpose of these discipline specific pages is to display content that might be of interest to faculty who are considering adopting open educational resources for use in their classes. This list of content is by no means exhaustive.  The nature of open educational resources is very collaborative and it is in that spirit that we encourage any comments about the content featured on this page or recommendations of content that are not already listed here. 


Calculus eBook - Dr. Kurt Gramoll

This Calculus eBook written by OU professor, Dr. Kurt Gramoll, features all of the main topics of Calculus. Each topic is divided into a number of sub-categories that broadens the user's understanding as well as supports the main concepts of Calculus.  Each sub-category is further divided into a case introduction, theory, case solution, and a simulation which the user can manipulate, giving the opportunity to enhance the user's understanding of the material. Author: Dr. Kurt Gramoll, University of OklahomaThe contents of eCourses are licensed under a Creative Commons Attribution-NonCommercial-ShareAlike license.

 American Institute of Mathematics Approved Textbooks

This is a collection of openly licensed Math textbooks approved by the American Institute of Mathematics. Books span Liberal Arts Math, Precalculus, Linear Algebra, Discrete Structures, and Complex Analysis among others.

"To gain our seal of approval an open source mathematics textbook must be able to serve as the primary text in a mainstream mathematics course at the undergraduate level in U.S. colleges and universities. That means that we are not evaluating instructional modules, Java applets, supplementary lecture notes, or other materials that are designed for limited use within a course. Since the minimum length of a traditional course is 10 weeks with 30 hours of class instruction, the books we evaluate must have enough material for that, and most will have more since most college courses are 14 or 15 weeks in length with at least 40 hours of class time."

 College Algebra, College Trigonometry, Precalculus  -Carl Stitz and Jeff Zeager

The material [in these books] is presented at a level that de finitely prepares a student for Calculus while giving them relevant Mathematics which can be used in other classes as well. Graphing calculators are used sparingly and only as a tool to enhance the Mathematics, not to replace it. The answers to nearly all of the computational homework exercises are given in the text and we have gone to great lengths to write some very thought provoking discussion questions whose answers are not given. As a contribution to the open-source community, all LaTeX files used to compile this book are available for free under a Creative Commons license at the author's website. -Stitz Zeager

In addition to our own two schools, we learned that 26 institutions across the US (and some abroad!) have taken our materials, put in their own hard work, and made it into something for their students to use! We've helped roughly 7500 students save a collective $780,000! (If the stats from our own schools are included, those numbers soar to roughly 13,000 students and $1.2 million!) 

College Algebra book reviews are available via Open Textbook Library.

 Calculus  -Gilbert Strang

Published in 1991, this book is a resource for educators and self-learners alike. It is well organized, covers single variable and multivariable Calculus in depth, and is rich with applications. There is also an online Instructor's Manual and a student Study Guide. In addition to these text-based materials, Strang has developed a video playlist, the Big Picture of Calculus in which he explains the conceptual highlights of Calculus.

 Elementary Differential Equations with Boundary Value Problems  -William F. Trench

Elementary Differential Equations with Boundary Value Problems is written for students in science, engineering, and mathematics who have completed calculus through partial differentiation. This text includes 1695 numbered exercises, many with several parts ranging in difficulty from routine to very challenging. Written informally, this book is mathematically accurate and is illustrated by appropriate graphics. This text is accompanied by its solution manual.

 Street-Fighting Mathematics -Sanjoy Mahajan

Street-Fighting Mathematics — the title refers to the fact that in a street fight, it’s better to have a quick and dirty answer than to stand there thinking about the right thing to do — is based on the premise that we can and should use rapid estimation techniques to get rough answers to difficult problems.  There are good reasons for preferring estimation over rigorous methods: the answer is arrived at quickly, the full set of input data may not be needed, and messy calculus-based or numerical techniques can often be avoided.  Perhaps more important, by avoiding a descent into difficult symbol pushing, a greater understanding of the problem’s essentials can sometimes be gained and a valuable independent check on rigorous — and often more error prone — methods is obtained.

 Elementary Differential Equations  -Dr. Andrew Bennett

This is an online textbook by Dr. Andrew Bennett of the Kansas State Mathematics department.  This text was developed specifically for Dr. Bennett's class and is therefore a little more direct than a traditional textbook. 

Dr. Andrew Bennett has not CC licensed the content, but it is publicly available.  

 Calculus (in three semesters) -University of Wisconsin

At the link, there can be found all necessary course materials for three semesters of Calculus instruction.  The material is separated in a traditional way.  The textbooks available here can be downloaded with answers and without.  Latex and figure files are available for download and modification if desired.  Supplementary material is also included here including project files, tips on grading projects and condensed study material for students on topics including, basic Trig. properties, epsilon-delta definition of a limit, and when not to use L'Hopital's rule.
