MATH 348 - Fall 2015 Be yourself; everyone else is taken. Instructor: John Lund Office Wilson 2-230 TEXT: Partial Differential Equations and Boundary value Problems, Nakhlé Asmar. Has a blue cover and the ISBN number is 0-13-958620-2 References Texts: A lot of material can be found in your math 274 text Fundamentals of Differential Equations, by Nagle, Saff and Snider (NSS) or Advanced Engineering Mathematics by Zill and Cullen, 3rd edition (ZC). 1. A review of second order Ordinary Differential Equations (ODEs). pages 508 - 514 Exercises 3,7,15,21,23 which are discussed in Chaptes 2 and 3 of Z/C. Just a little of first order and a fair amount of second order. Existence and uniqueness, linear dependence and independence, homogenous solutions, the Wronskian, non-homogeneous solutions, reduction of order, second order linear equations (with constant coefficients). 2. Series solutions of ODEs. Power series solutions, singular points, and the method of Frobenius. Two examples: The Bessel and Legendre differential equations. 3. Fourier Series. Orthogonality, Fourier Series and the half-range (cosine and sine) expansions. 4. Introduction to the heat equation. There will be four homework assignments (total of 100 points) and four 50 point written tests at (more or less) equal time intervals. Your final grade will be based on 300 points. Below is the grading scale.
