Students in this class will be required to
- write bounds on definite integrals
- write arguments to functions
- use different symbols for integration variables and variable outside integrals (e.g. in variation f parameters)
- write equations and inequalities, not just expressions (=,< or > must appear somewhere in each mathematical statement)
- put answers to exam questions in a specified place

Homework:
Note that problems marked with a mouse in the book could be helped by
use of a computer. For these problems, you must show all steps in the
analytical solution of the problem (if this applies). The mouse often
indicates that the computer can be used for a plot.

- 5.4 (p. 271) first problem after #2 with a regular singular
point: Find the indicial equation and the first 4 terms
in the series expansion around a nonzero singular point (or around
x=0 if that is the only regular singular point) for the solution
found by techniques in section 5.6. For this problem, I don't care
about the second solution described in Theorem 5.7.1 on p. 291.
My apologies about not specifying the problem number: I forgot to
check if problem 2 had a regular singular point, and I don't have
my book at home.
