The goal of this text is to help students master both subjects in a one-semester course. The linear algebra necessary for applications is developed first and continually referenced when solving ODEs. The discussion of ODEs focuses on solving linear problems since they are most relevant to undergraduate science courses that require an ODE background. Separable equations and nonlinear systems are also covered. The second edition of Ordinary Differential Equations and Applied Linear Algebra expands the learning experience by introducing case studies at the end of every chapter. The case studies include SIR models, a model for lead poisoning in the human body, and a study of the dynamics of strongly damped forced oscillators. Also present are end-of-chapter projects that allow students to explore the interplay between the creation of a mathematical model, the solution of the model, and the physical implications of the mathematical solution. Specifically, projects deal with the ranking of web page importance through the Google PageRank algorithm, the study of pollution flow in the Great Lakes, a compartment model for lead poisoning in the human body, and glucose/insulin interactions in the bloodstream, among others. Also new to the second edition is access to over 300 online homework problems embedded within the CMS myOpenMath.

In 1990, the Copper Mountain Conference on Iterative Methods was formed as a companion conference to be held in even years. Together, they are widely regarded as premier international conferences on iterative and multigrid methods. In 2026, we continue this conference series with the Colorado Conference on Iterative and Multigrid Methods to be held on the CU Boulder campus. Abstract submission and registration for the conference are now open.
