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 definitely 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 opensource 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 College Algebra book reviews are available via Open Textbook Library.

Published in 1991, this book is a resource for educators and selflearners 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 textbased 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. William F. Trench Author: William F. Trench, Ph.

StreetFighting Mathematics Sanjoy Mahajan StreetFighting 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 calculusbased 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 therefor 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, epsilondelta definition of a limit, and when not to use L'Hopital's rule.
