Announcements for Math 308 D and E, Spring 2012

• June 8: Solutions for the final. I am only posting version B; version A had the same problems, but in a different order.
  

• May 24: Final Review: Friday June 1st, 3-6pm, SMI 211.

• May 21: Solutions to Quiz 2: version A, version B.

• May 15: The Quiz 2 material consists of chapters 5.1, 5.3, 3.6, and 7.3 (orthogonal bases, Gram-Schmidt, linear transformations, and least squares).

• May 15: The Calendar has been updated to reflect the fact that we will be spending more time on Determinants.

• May 6: The solutions to the midterm can be found here: version A, version B.

• April 23: For the Midterm, you will be allowed to bring a double-sided, A4 (8.5x11) sheet of paper with handwritten notes (a "cheat sheet").

• April 23: The Midterm Review will be held in SMI 211 (Tuesday May 1st, 3-6pm). You will be allowed to bring an A4 (8.5x11) sheet of paper with handwritten notes (a "cheat sheet").

• April 20: Solutions for the quiz: version A, version B. Unfortunately, I scanned them in reverse page order!
  

• April 11: Due to time constraints, we could not cover elementary matrices in class. Please read about them in the book (end of chapter 3.3). We will state, but not prove, the Fundamental Theorem of Invertible Matrices in class on Friday.

• April 9: Quiz 1 is on material from the first two weeks only.

• April 2: For HW 1, problem 14, the format of the answer implies that you need to consider "x" as your free parameter. This becomes a lot easier if you cycle your variables; instead of (x,y,z) think of (y,z,x), rewrite the equations, bring to echelon form, set x=t, solve for y and z, and then extract the constants from the answer vector and factor out the "t" in what remains. (Hint: since x=t, what is the first number you will need to enter in WebAssign?...)

• April 2: The date for Quiz 2 was mistakenly listed on the main course website as May 25th; the correct date is May 18, and I have made the correction.

• March 27: The Office Hour on Monday has been pushed to 1:20 - 2:20pm, in PDL C-342. The Tuesday Office Hours at the MSC (1:30-3:30pm) will take place in CMU B-014B, the small room located to the right as you walk in.

• March 26: Introductory class. The Course Outline was distributed on the first day. Check out the Calendar, which will be updated as we go along.
