Homework Set 10: Due Friday, November 9.

Show all work. Convince me that you are not just copying from the 
back of the book.

5.1: 3, 7, 11, 13, 16.

5.3: (Not 5.2!) 2, 4, 5, 7 12, 13, 14, 21

If you would like to do an Extra Credit Project, do problems 22-29
in 5.3 on Legendre's Equations. Turn in separately.

5.2: Follow the directions of 5.2 1-14 (page 247) but use these four 
equations:

a) y''+ xy'-y = 0 (center=0)

b) (2+x^2)y'' + 4y' + y = 3 (center = 0)

c) xy'' + xy' + 3y = 0 (center=2)

d) y'' + y' - xy = x^2 (center = 3)

Hint: Do some of the textbook's problems first.
