HOMEWORK SUMMARY REPORT
Chapter number: 7
Section number: 5
Exercise number: 2
Number of papers received: 1
Reviewing committee: delta
List all participating committee members:
Stacy Lodden, James Jarczyk
Author(s) of paper(s) chosen for publication: Todd Anderson
Comments: There was only one paper submitted, and thus was chosen for
publication by default. The solution is well-done, however, and has
logical explanations for all steps and so does snot require revision.
GRADER'S COMMENTS: (1) In part (b) the \sigma mysteriously disappeared.
(2) He proved the eigenfunctions were real, but the problem was to prove
the eigenvalues are real.
(3) "Sturm-Liouville form" is not enough to conclude that eigenvalues are
positive. (Use integration by parts; see the old solution.)
(4) Zero is not an eigenvalue of this problem. (See the old solution.)
