Elementary Engineering Mathematics

This page contains links to notes, equation sheets, and recommended exercises for topics in elementary engineering mathematics. The material covers the application of mathematics to introductory engineering problems. Topics include mechanical and electrical engineering applications using algebra and trigonometry, vectors, sinusoids and harmonic functions, systems of equations and matrices, simple derivatives and integrals, and simple linear differential equations.

The course material is intended to help students:

  1. Learn to apply mathematics in the solution of introductory engineering problems
  2. Learn how mathematics is used throughout their engineering curriculum
  3. Strengthen their basic mathematical skills

These course materials were developed based on EGR 101 Introductory Mathematics for Engineering Applications; a course taught at Wright State University. EGR 101 was developed under a Course, Curriculum and Laboratory Improvement (CCLI) grant from the National Science Foundation (NSF). In Phase 3 of this project entitled “A National Model for Engineering Mathematics Education,” similar courses were developed and taught in engineering programs at various universities.
