Introduction to ordinary differential equations. Topics include first order equations (separable, linear, homogeneous, exact, substitutions); linear second order equations (method of undetermined coefficients, variation of parameters); applications (oscillations and resonance, circuits); Laplace transform; power series solutions. Only one of MATH 324 and MATH 371 can be counted towards Math minor. Prerequisites: C- or better in MATH 227 or MATH 230. Every semester.
