There are two mistakes near the bottom of page 21 of the Chapter 10 hand-out. The last three sets of equations should read:
v"(x)=av(x) (this one is correct)
w"(t)=aw(t) (instead of w"(t)=av(t))
v(0)=v(pi)=0 (instead of v(x)=v(pi)=0)

There is a mistake on page 10 of the Section 8-3 hand-out. In the middle of the page, the eigenvalues for J should be 1 plus or minus *i times* the square root of 3, all over 2.

Hard copies of homework solutions are now available on reserve in Cabot Library.
