Math 341 has two major themes.Â One is the development of a method of solution of certain partial differential equations.Â The other is a careful examination of some of the surprising consequences of that method.
The partial differential equations considered are the heat equation, Laplaceâ€™s equation, the wave equation and SchrÃ¶dingerâ€™s equation.Â Examination of the method (called Fourierâ€™s method) leads to expressing a given function as an infinite series (a Fourier series) of sines and cosines. Â
