This is a copy of the detailed syllabus that evolved on the Sakai site. It is similar to that used in Spring 2009, except that homework will be due in the class following the one in which it is assigned, and more quizzes will be scheduled.

1. Jan. 20 (first class): Definition of Laplace transform; calculation of transforms and inverse transforms; partial fractions.
   • 4.1: 12, 26, 38.
   • 4.2: 8, 16, 18.

    • 12.5: 8, 10.
    • 5.1: 20, 24, 30 (For 20 and 24, solutions should be written as a sum of two special solutions, one solution with y(0)=1 and y'(0)=0, and a second solution with y(0)=0 and y'(0)=1. For all problems, "solution" should be interpreted as "the first four nonzero terms of the series solution, which you may follow by "..." if you like, unless the solution is a polynomial with fewer terms".)
14. Mar. 08: Review of complex Fourier series, Sturm-Liouville problems; series solutions of differential equations.A detailed syllabus will evolve here.

    • 12.6: 16, 22.
    • 5.2: 18, 20, 28 (For all problems, "solution" should be interpreted as "the first four nonzero terms of the series solution, which you may follow by "..." if you like, unless the solution is a polynomial with fewer terms". Showing the series automatically gives the solutions of the indicial equation and allows a trivial verification that the roots do not differ by an integer. You should do those steps, but it is not necessary to say that you did them.)

Supplements

The following supplements produced during the term have been copied here.

1. Overview of Laplace transforms. An overview of the properties of Laplace transforms.
2. An operational view of Fourier series. A (not completely successful) attempt to apply the operational method used for working with Laplace transforms to Fourier coefficients. The text insists on explicit evaluation of the integrals for the Fourier coefficients every time they are encountered, instead of remembering previous results and quting them when a similar quantity is to be expanded in a Fourier series. In particular, the use of integration by parts to find the Fourier coefficients a function in terms of the coefficients of its derivative exposes one to errors that are easily avoided.
3. Boundary Value Problems. An expanded treatment of the Sturm-Liouville theory. The treatment in the text was far too brief, so these notes gave more details about the eigenfunction expansions that would be used in the solution of the classical partial differential equations.
4. Partial Differential Equations. Additional information about the wave equation and heat equation in one dimension. In addition to results obtained by the method of separation of variables, there is a description of d'Alembert's solution.
5. Vector Calculus. An attempt at describing "div, grad, curl, and all that" (as the subject is characterized in the title of a book on the subject). This provides the background for the appearance of the Laplacian in other coordinate systems.

Other supplements dealt with solutions of individual homework exercises. They will not be made available outside of the Sakai site.

History

There is a similar version of the course from Spring 2009. The syllabus on that page may be considered to be a good approximation of the plan for this semester.
