Homework 3, Due at the beginning of class, Tuesday Feb. 8, 2005.

Be sure to
  • write your name and ID on every page
  • make a copy of your homework for your own records and exam study
  • staple (not paper clip) your pages
  • write clearly
  • show your work -- an unannotated sequence of numbers and derivations that mysteriously ends up with the correct numerical answer will not be given full credit
  • answer every part of every question (unless instructed otherwise).
