Multivariable Calculus Text (Supplement to Open Stax Text)
Karla Westphal · Saddleback College
This is a supplement to OpenStax Calculus V3. It is meant to substitute for section 4.2, limits of functions of more than 1 variable, placing less emphasis on using the definition directly and more on techniques like substitution, changing coordinate systems, and paths.

Calculus for Business and Social Sciences Corequisite Workbook
Victoria Dominguez, Cristian Martinez, & Sanaa Saykali · Citrus College
This text serves as a Corequisite Workbook for an Applied Calculus course. It is vitally important for students who take this course (and its corequisite) to have a thorough and complete refresher of Algebra skills needed for Calculus. These problems may be assigned as in-class practice problems, and can be also assigned as homework, to be graded and counted toward the Applied Calculus corequisite final grade.

Matrix Algebra with Computational Applications
Dirk Colbry · Michigan State University
Matrix Algebra with Computational Applications is a collection of Open Educational Resource (OER) materials designed to introduce students to the use of Linear Algebra to solve real world problems. These materials were developed specifically for students and instructors working in a “flipped classroom” model that emphasizes hands-on problem solving activities during class meetings, with students watching lectures and completing readings and assignments outside of the classroom.

Math 098: Intermediate Algebra for Calculus
Highline College
This text introduces a variety of algebraic techniques and functions that will prepare you for calculus. Focus will be placed on quadratic, rational, and radical functions with emphasis on algebraic techniques used to combine and simplify them. Techniques will include factoring, simplifying (adding/subtracting/multiplying/dividing) polynomials, rational and radical expressions, and relationships between equations and their respective functions and graphs.

Introduction to the Modeling and Analysis of Complex Systems
Hiroki Sayama · Binghamton University, State University of New York
Introduction to the Modeling and Analysis of Complex Systems introduces students to mathematical/computational modeling and analysis developed in the emerging interdisciplinary field of Complex Systems Science. Complex systems are systems made of a large number of microscopic components interacting with each other in nontrivial ways.

Abstract Algebra: Theory and Applications
Thomas W. Judson · Stephen F. Austing State University
This is an open source textbook designed to teach the principles and theory of abstract algebra to college juniors and seniors in a rigorous manner. Its strengths include a wide range of exercises, both computational and theoretical, plus many nontrivial applications. The first half of the book presents group theory, through the Sylow theorems. The second-half is suitable for a second semester and presents rings, integral domains, Boolean algebras, vector spaces, and fields, concluding with Galo

Math 126: Calculus with Review II
Katharine Vance · Hope College
This course is a continuation of Math 125. The topics covered are the topics typically taught in the second half of a Calculus I course. The calculus material in the course is supplemented by reviewing topics of high school mathematics as needed. The calculus topics are also taught at a slower pace. Topics include implicit differentiation, applications of differentiation, L'Hospital's rule, Newton's method, the integral, and applications of integration.

Friendly Introduction to Mathematical Logic
Christopher Leary & Lars Kristiansen · SUNY Geneseo & University of Oslo
At the intersection of mathematics, computer science, and philosophy, mathematical logic examines the power and limitations of formal mathematical thinking. In this expansion of Leary’s user-friendly 1st edition, readers with no previous study in the field are introduced to the basics of model theory, proof theory, and computability theory. The text is designed to be used either in an upper division undergraduate classroom, or for self study.
