Due Dates

The takehome midterm and all homework rewrites (up to homework 8) are due by Thursday, March 15, 5pm.

Homework 9 is due at the start of the final exam, Friday, March 23, 3pm.  It will not be graded; I will merely mark which problems you attempted.  However it's very important to do the problems to study for the final!

Math 110BH Notes

An excellent set of notes for Math 110BH by Andrew Nguyen can be found here.

Textbook Errata

Errata for the second and third editions of the textbook can be found here.


Information on using latex to typeset your homework (or use in general) can be found here.


Homework is posted on the class webpage.  It is due in section on the date posted.  You may also leave it on my desk or under my office door before 5pm on the day it is due.  Note that you can no longer leave homework in the mailroom.  I'll grade the homework and return it in section the following Thursday.

Homework Grading

I plan to grade about 4 problems per week.  Each problem will be worth 2 points.  The general rule is that you get 2 points if the problem is completely correct (or very close), 1 point if it is not completely correct but is at least half correct, and 0 points otherwise.  You are expected to redo problems that you get fewer than full points on, and you are allowed to redo problems several times (but try very hard to get it right the first or at least second time!).  I highly recommend doing your homework in LaTeX which will make it much easier to revise solutions.  Note that I will only grade hardcopy solutions, so you must print them out rather than sending them to me via email.

I will try to grade homework over the weekend after it is due, and you may be able to stop by my office as early as Monday if you want to see if you need to redo problems.  Otherwise I'll hand back homework in section.

Homework Rewrites

For rewrites, please hand back your original homework (along with any previous rewrites) with the rewritten problems. If you just missed some detail it is fine to just write in the missing detail on the original homework (or last rewrite), but make sure to emphasize it somehow (different color ink, box around it, or whatever), so that I can find it. For more substantial rewrites it's better to completely redo the problem on a separate sheet of paper and attach it to the packet. Make sure to clearly indicate which problems you are redoing. There is no specific due date for rewrites, but it's good to get them in soon while the problem is still fresh in your mind. Be sure your rewritten solution is really correct to avoid having to redo the problem once again. I'll grade rewrites when I have the time, but will give higher priority to grading new homework problems.

Homework Solutions and Comments

Homework solutions and comments for graded problems will be posted here when they are available.  I will post solutions for non-graded problem, and comments for graded problems that will be replaced by solutions when everyone has redone the graded problem to satisfaction.  You are expected to self-grade the problems I don't grade (feel free to ask me if your solution differs from mine and you have some doubts about it) and to read the comments for the problems I do grade.  I'll note when a given solution document has been revised.
NOTE:  Complete homework solutions and comments for the takehome midterm are now posted.
