    • Final project abstract which includes a list of references at the end of it (references are not included in the word count) due by 12:00pm as an electronic file I can read with University software posted to the WebCT bulletin board. This file will be posted onto the main web page.

    June 30 - Wed
    • Complete and correct Test 2 revisions due for +15 (See WebCT posting on this). If the revisions are not complete and correct, then you will receive 0 extra points. I'm happy to check over them for you in office hours before they are due.
    • Test 3 study suggestions

    June 22 - Tues
    • Read over PS 6 solutions and the study guide for the test
    • Read over WebCT posting about test 2 revisions, and begin working on them.
    • Final project proposal (a short description of what you plan to do) and preliminary list of references due by 5pm. Your topic needs to be pre-approved by me as there is a limit to the number of people per topic.

    June 28 - Mon
    • PS 6 due at 5pm - See Problem Set Guidelines and Sample Problem Set Write-Ups
      7.1 #14 by hand and on Maple via the Evectors(A); or Eigenvectors(A); command -- also compare your answers and resolve any apparent conflicts.
      LAMP Module 6.1 Problem 4 Parts A and C: Rotation matrices in R2 Note: To print out geometric pictures for part A, use Headtail(M); on specific rotation matrices such as M:=Rotatemat(0); This gives a static picture, instead of Clock(M); which gives an animation that won't print out. Note: Headtail only seems to work on Macs - not on PC's! Also, in part C, look at the eigenvalues and solve for the possible theta that will yield real numbers (recall that the square root of a negative number does not exist as a real number and that cos(theta) is less than or equal to 1 always.) Ignore the portion of part c that refers back to part b.
      7.2 7, 18, and 24
      LAMP Module 6.3 Problem 4 Part A: More foxes and rabbits (Predator-prey model). Hint See p. 348 Section 3 and Example 3A up until about 1/3 the way down on p. 349 "tend toward the zero vector in the limit." and complete a similar analysis after following the directions by changing the setup in section 4.
      EXTRA CREDIT for Part B
