AnnouncementsNotes and FAQ1/9/06: (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. Class Policy Statement

Homework/Projects: Homework will be assigned in class and collected in accordance with the syllabus, and will be usually returned within one week. Although collaboration in solving most problems is encouraged, it is strictly forbidden to copy someone else's homework. It is expected that cocollaborators and other sources for the homework will be duly acknowledged. For some specified problems no collaboration will be allowed. The official programming language for this course is Matlab. Prior experience in Matlab is not required. Current information about the course will be available through Blackboard and the 384H homepage. Using the web is strongly recommended for keeping track of current activities in the course. Reading Assignment: Read the sections of the texts as, or before, they are covered in class lectures. This is a standing assignment throughout the semester. Grade: One midterm will be given and will account for 135 points. The final exam will count 140 points. Each exam may have a take home component. Inclass exams are closed book with calculators. Homework will count 225 points. The final grade will be based on these 500 points. Final Exam: Will be comprehensive. To be given on Tuesday, May 1, 10:00  12:00 am in 110 Kauffman. Grades of "I", "W" or "P": These grades will be given in strict accordance with University policy. (See any Schedule of Classes for the relevant information and dates.)
