Final Exam scores now visible; Extra Credit totals now visible

Dear Class,
Thanks for all of your dedication and hard work. It was a pleasure for me
to teach you.
You can now see all of your scores (except final letter grades which
must be go through a process that takes a few days)
1. final exam scores (out of 180)
2. total score as a percent of 100 (not counting extra credit)
consists of 30 percent for the two hour tests; 30 percent for homework;
40 percent for the final.
3. separate extra credit score computed from all extra credit during the term
as a percentage that is added to the total in part 2

Your letter grade is computed by adding the total in 2 and 3 to get
an overall percentage.
Grade cutoffs are 80 percent for A-, 70 percent for B-, 60 percent for C-,
50 percent for D.

Corrections to notes

Good luck on the final exam!! I don't think you will need these corrections, for the exam, but I do need to send them. There are several mathematical misprints in the notes that were pointed out in the review session:

Chap 7 notes
page 1
0 < x < \le 1 (omit extra \le sign)

page 7 two lines from the bottom:
diameter less than \epsilon not \delta

page 8
there are J^L such functions \alpha (not L^J)

Estimates and asymptotics page 8
there is an extra factor \alpha that is wrong.
the integral is (1/2)\sqrt{\pi} \alpha^{-3/2} not -5/2.
