Subscripts d corrected to p. (Zoltan Toth) Typo: Theorem GESD, 2 typos, and a missing identity matrix at end. (Zoltan Toth) Typo: Theorem GESD, T:V->V in hypothesis. Typo: Solution EE.C24, wandering minus sign in eigenvector for eigenvalue 3 (Amherst student). Typo: Removed ten stray instances of exam "points."
