Notes and FAQ
1/9/06: (Just to get the FAQ started) About significant digits...
I've been asked to explain what significant digits of an approximation to a number mean. Here goes: to get the number of significant digits, first *subtract* (rather than just looking at the numbers) the two (may as well be larger - smaller,) then find the position of the leading digit of the error relative to the position of leading digit of the exact answer. (We're thinking in fixed point representation in this discussion.) If the difference in that position is at most 5, then number of significant digits is one less than that position, else two less.
For example if 1.006 and .995 are used to approximate 1, calculate 1.006 - 1 = 0.006. Notice I put the zero in front of the decimal to start counting from the right position. There is disagreement at the 4th position, counting from the (base 10) position of the leading digit of 1, and the size of this disagreement is greater than 5, so this approximation has 2 significant digits. On the other hand, 1 - .995 = 0.004, which again first disagrees in the 4th position, and the size of the disagreement is at most 5, so .995 has 3 significant digits as an approximation to 1. BTW, it's also perfectly correct to say that each answerhas one significant digit, though this doesn't give all the available information. Hope this helps.

The times listed below are approximate, and may be adjusted as the semester progresses. The two sources for material are the class textbook (BT) and my own prepared notes (NT). Assignments are due on Tuesday if they are listed first below, and Thursday otherwise. Unless otherwise stated, you should turn in hardcopy of your work. The specifics of each assignment will be given in class and posted on the web as the course progresses. Problems that are to be worked by individuals without collaboration will be marked ``(I)''. Each assignment will be worth 45 points. Each assignment includes all problems not yet collected and assigned one week or more before the due date.
Friday, January 19, is the last day to withdraw from the course and not have it appear on your transcript.
Friday, March 2, is the last day to change your grade option to or from ``Pass/No Pass''.
