News & Announcements

08/07 I posted the final exam grades and final course averages on AsUlearn. Final letter grades 
      are posted as comments in the course averages.

      If you want to look over your exam, I'll keep them around for at least a year. Also, if you 
      ever have an questions, mathematical or otherwise, please don't hesitate to send me an email! 
      I'm happy to help if I can.

      Have a great (what's left of the) summer!

07/30 Test #2 is Wednesday (August 1st). You are responsible for material covered
      since the first test (through today). Specifically...

      Chapter 2 Sections 2.3, 2.4, 2.8, 2.9 -- You may skip LU-factorization (2.5) and the application sections.
      Chapter 3 Sections 3.1 -- 3.3
      Chapter 4 Sections 4.1 -- 4.7
      Chapter 5 Sections 5.1 -- 5.4 

      Keep in mind that there is a fair amount of redundancy between chapter 2 and 4 stuff. Also, 
      we discussed coordinate matrices earlier than they appear in the text (in section 5.4). 
      You may want to refer to our handouts:
      Computing Kernels and Ranges, Coordinate Matrix Example, and An Eigenhandout.

      I recommend looking at your quizzes, notes, and suggested homework when studying. In addition, I have several 
      old tests posted. However, these do not correspond to our current text. The following problems are relevant...

      Fall 2012: Test #2 -- problems 2-5.
                 Test #3 -- all of it.
                 Test #4 -- all of it.
              Final Exam -- problems 5-10.
 
    Spring 2011: Test #2 -- problems 3-6.
                 Test #3 -- all of it.
                 Test #4 -- all of it.
              Final Exam -- problems 4-10.

      Fall 2008: Test #2 -- all of it.
                 Test #3 -- all of it.

    Spring 2008: Exam #1 -- problems 2 and 5.
                 Exam #2 -- problems 1-6.

      Fall 2006: Exam #1 -- problems 2, 5, and 8.
                 Exam #2 -- all but problem 4. 

    Summer 2006: Exam #1 -- problems 7 and 8.
                 Exam #2 -- all but problem 3.
              Final Exam -- problems 3,6, and 9.

07/27 Homework #2 (.pdf) [Source: (.tex)] is due Friday, August 3rd.

07/18 A few helpful tips for doing linear algebra in Maple: (.mw) and (.pdf)

      Homework #1 (.mw) [Print out: (.pdf)] is due next Wendesday, July 25th.

      You may work on this homework together. You do not have to complete it in Maple. However, some of the problems might
      be really tricky to do in Matlab (I honestly don't know). If you use other software, make sure you attach a print out
      of the code/commands you used to find answers.

      Here is an example of computing/using the PLU decomposition in Maple (created for my grad class)...
      PLU Decomposition (.mw) [(.pdf)] and row operations in Maple.

      Here is a handout for tomorrow...

      Here is a demo for tomorrow or Friday...
      Visualizing Determinants (.mw)

07/13 Test #1 is Tuesday. It will cover chapter 1 (sections 1.1-1.9 we skipped 1.10), sections 2.1-2.2, and
      the Linear Correspondence material from our handout.

      You will not be allowed to use a calculator for at least the first portion of the test. I will try to better 
      clarify this on Monday. 

      I recommend looking at your quizzes, notes, and suggested homework when studying. In addition, I have several 
      old tests posted. However, these do not correspond to our current text. The following problems are relevant...
      
        Fall 2012: Test #1 -- all of it.
                   Test #2 -- problem 1.
                   Test #3 -- problem 3ab and problem 6 sort of applies.
                   Test #4 -- problem 1a and if 1-1 or onto.
                Final Exam -- problems 1-3,5c,6c,9a (just finding the matrix and if 1-1 or onto), 
                                       and problem 8a sort of applies.

      Spring 2011: Test #1 -- all of it.
                   Test #2 -- problems 2 and 6b.
                   Test #3 -- problems 3, 4a and problem 6b sort of applies.
                   Test #4 -- problem 1a and if 1-1 or onto.
                Final Exam -- problems 1-3,5b,6c,9a (just finding the matrix and if 1-1 or onto), 
                                       and problem 8a sort of applies.

        Fall 2008: Test #1 -- problems 1-4,6.
                   Test #2 -- the first two parts of problem 3.
                   Test #3 -- problems 2a and 3a sort of apply.

      [Rutgers]
      Spring 2008: Exam #1 -- problems 1a,2-5,6ab,7b.

        Fall 2006: Exam #1 -- problems 1a,2-5,6ab,7,8.

      Free Math Tutorial Center
      General Math Lab is held in Walker 309 Monday-Friday 3 to 6 pm. It opens the first day of 
      classes for each session. 

      It is intended for assistance in most 1000-2000 level Math coursework (except Math 1030). 
      This lab is staffed by math tutors, graduate assistants, and Math Department faculty.

      Greetings!

      The math tutor lab will be open the first day of classes, both sessions. We will 
      be open from 3-6 pm, Mondays - Fridays, in Walker 309. Our tutors can handle 
      Business Math, all maths from 0010 - Calc 3, Proofs, Real Analysis (I hope; they've 
      taken it), DE's, Linear and Modern. 

      Please let me know if you have any concerns or questions.

      Thanks,
          Lisa

      We may use "Maple" a few times this session. Maple is a "computer algebra system" 
      (math software) and is available -- theoretically -- on all campus computers. 
      Math majors are likely to encounter this software many times as they take courses
      in their major. Geology, Physics, and several other majors may run into it again
      as well. If you would like to purchase a copy of Maple, you can get it for about 
      $75 with the discount code: AP97261-713F0
