News and Announcements
| 2/19/12 | I have finished grading exams. See this webpage for information
on grades, other comments on the exam, and an assignment to writeup exam
corrections. Don't forget that writeups from the last
computer lab are due tomorrow (Monday 2/20). |
| 2/15/12 | I thought of one
more good review question for our exam tomorrow. We can talk
about it at the review session tonight. Also, solutions to the sample exam questions have been posted. |
| 2/14/12 | We will have a review session for the exam in Watkins room 106 on Wednesday, February 15 from 8:10pm to 9:40pm. |
| 2/12/12 | Here are solutions to selected * and extra problems from section 1.4, section 1.5, and section 1.7. |
| 2/10/12 | 1.
For those who missed the computer lab Thursday, you can complete it on
your own using the following two handouts:
3. Assignments for sections 1.7 and beyond are provided on the 2nd Assignment Sheet. I have modified the assignments from sections 1.7, 1.8, and 1.9. For any of these assignments that you have not already done, please use the newly posted versions. You should complete these assignments in preparing for the exam. 4. We will have an exam in class next Thursday (2/16/12). Information about the exam is available here. It includes information about planned class activities Monday, a possible review session Wed evening, and a sample exam. |
| 2/8/12 | Here are solutions to selected * and extra problems from section 1.3. |

We
will be meeting in the SPA Computer Lab on Thursday, 2/9. For the
lab period we will be using the following webpage: http://mathcs.holycross.edu/~spl/java/Transform/index.html . If for some reason that is inaccessible during our lab period, the following website will be used as a back-up: http://www.math.smith.edu/~patela/Applets/transf_index.html . |
| 2/5/12 | Here are solutions to selected * and extra problems from section 1.2. |

Here
are solutions to selected * and
extra problems from section 1.1. |

Reminder:
Class will
meet in the SPA computer lab on Monday. That is in the
sub-terrace level (2 below ground level) in Ward. You can access
that level from the stairwell in the corner of Ward that is furthest
from the Mary Graydon Center. In class yesterday I highlighted
some of the main ideas from sections 1.1 and 1.2. In the computer
lab you will get ac chance to work with some of those ideas using
computers. In preparation, it is important that you understand
how to change a system of linear equations into a matrix form (and what
is meant by an augmented matrix), know the three kinds of row
operations, and how those operations are used to bring an augmented
matrix to a simplified form. In general terms the idea is to try
to get 1's in a diagonal line from upper left to lower right, and zeros
everywhere else, but that is not always possible. There is a
modified version of this diagonal pattern that IS always
possible. That is referred to as Reduced Row Echelon Form (RREF),
and it is defined on the first page of section 1.2 (there are 5
conditions). In the lab you will be asked to use row operations
to put a matrix into RREF, so be sure you know what that means before
class. No homework problems will be collected or discussed on Monday. You should read carefully up to the middle of page 20 and familiarize yourself with the terminology and concepts. The assigned problems for section 1.1 will be due for discussion Thursday and collection the following Monday (1/30). Homework problems from 1.2 and 1.3 will be due for discussion on Monday 1/30 also. |

Activities and Tools.
Math majors, minors, potential majors and minors, and students planning
to take advanced math courses (500 level) should also
read Note for Math Majors, Minors, and
others. Also,
please print out a copy of this survey, fill
it out, and then bring it to class. For information about the text for the course, or if you will not have a copy at the start of classes, please read this page. |
