This course provides an introduction to ordinary differential equations and their applications. Analytical methods include: separation of variables, linear first order equations, substitution methods, second order linear equations with constant coefficients, undetermined coefficients, variation of parameters, dynamical systems, series solutions about ordinary points, and the Laplace Transform. In addition to analytical methods, quantitative and qualitative analysis will be employed through the use of Euler's Method, phase lines, phase planes, and slope fields. Prerequisite: MTH 222- Calculus 2 with a grade of C or better or MTH 241- Calculus 3. 4 cr. 4 Lec.
