    • Test 3 on Chapters 1-4, 7, and computer graphics study guide
    • WebCT quiz 2 retakes due.

    June 23 - Mon
    1. Practice Problems 6.5 in the book numbers 13, 15, 17, 25, 33
    2. Test 2 Revisions Due at 5 - complete and correct revisions will result in a +5 added onto your course average.
    3. Problem Set 6 Due at 5 Guidelines
      7.1 (14 by hand and on Maple via the Evectors(A); or Eigenvectors(A); command -- compare your answers and resolve any apparent conflicts)
      LAMP Module 6.1 p. 322 Problem 4 Parts A and C: Rotation matrices in R^2 parts a and c. Note: if you want to print out geometric pictures, use Headtail(M); which gives a static picture, instead of Clock(M); which gives an animation that won't print out. 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.)
      7.2 6, 16 and 22
      LAMP Module 6.3 p. 357 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.
