Dr. Sarah's Math 2240 Class Highlights Spring 2004 Page

The following is NOT HOMEWORK unless you miss part or all of the class. See the Main Class Web Page for ALL homework and due dates.



  • Tues Apr 27 Go over LAMP Ch 4 Module 3 on Computer Graphics. Then work on Problems 1 and 3.
    Hints on Problem 1: Look at Section 1 example 1C, but use rotation by -Pi/6. We also need to shrink the triangle as it goes around, so, instead of letting M equal U.R.T, you need to add a dilation matrix A somewhere (using, for example, the command A:= Diagmat([1/2,1/2,1]); and M:=the product of the 4 matrices A, U, R, and T in some order that makes sense, and Movie(M,triangle, frames=18); but adjusting the dilation so that it matches the problem.)
    Hints on Problem 3: Try a rotation matrix composed with a translation matrix.
  • Tues Apr 20 Finish LAMP Ch 4 Module 1 Geometry of Matrix Transformations of the Plane. With a partner (groups of 2 around 1 computer), begin working on
    Chapter 4 Module 1 Problem 1: Guess the transformation
    Chapter 6 Module 4 Problem 7: Projection matrices
    Chapter 6 Module 4 Problem 8 Parts a and b: Shear matrices
    Go over the problems at the end of class.
