The exam is cumulative, with approx. 60% based on new (chapter 10) material. Location : 108 Forum (sections 1, 2, 9, 12), 100 Thomas (sections 3, 4, 5, 6, 7, 8, 10, 11) A table of Laplace transforms (a copy of table 6.2.1 from the textbook) will be provided during the exam. Topics to study All the topics from the midterm exams: Plus, 1. Separation of variables 2. Two-point eigenvalue problems; finding eigenvalues / eigenfunctions 3. Fourier series; Euler-Fourier formulas 4. The Fourier Convergence Theorem 5. Even and odd functions; even and odd periodic extensions 6.

Unformatted text preview: 8. Wave equation: vibration of a fixed-end elastic string Except: the topics below are explicitly NOT covered on the final exam: a. Mixing/compound interest/air resistance problems b. Reduction of order c. D’Alembert solution of the wave equation d. Lapalce/potential equation (section 10.8; note that this topic is different from Laplace transforms, which will be on the exam) Comments : Students should know basic integration techniques; partial differentiation; the Existence and Uniqueness theorems; the general long-term behavior of different types of solutions; the behavior of the solutions of various types of mass-spring systems; stability/ phase portrait classifications; Laplace transforms; computing Fourier coefficients and determine the convergence of Fourier series; finding the steady-state solution for simple nonhomogeneous boundary conditions; and each of the steps used to solve a second order linear PDE initial-boundary value problem....
