# Math Topics

Here you can find a directory of the content developed by the Engineering Math Resource Center for the various engineering mathematics topics you will learn in your math courses. Reference these to brush-up on topics that you have spent time learning and practicing or to give you some specific context into how these topics will be used in future engineering courses. Each of these pages will first give you a general overview of how that specific mathematical topic is used in engineering before providing a description of the topic in mathematical terms. Specific applications of the topic will then be given for each of the majors in engineering offered at USU. Finally, external resources will be provided so that additional practice and understanding can be found easily for the interested student.
