Text Book

Linear Algebra -- 4'th edition -- by Stephen Friedberg, Arnold Insel and Lawrence Spence

Course description

We shall cover most of the first six chapters of our text. In terms of topics these chapters include all the those covered Mat 211, plus some additional. Aside from covering more topics than is done in Mat 211, this course also differs from Mat 211 in that students are required to understand the many proofs of Theorems covered --- and sometimes (in homeworks or on tests) are required to recall these proofs or to develop their own proofs for elementary facts.


Many students find it helpful to read the corresponding sections of the text before attending each lecture.

Problem sets will be assigned weekly; check this webpage for the assigments. Each homework set is due during your recitation class of the following week (unless otherwises stipulated). Note that the solutions to some of the problems appear in the back of the text book. You should nonetheless try and solve these problems without recourse to the answer key, and should write the problem up carefully in your own words even if you have consulted the book for the final answer: always show your work.

It is OK to discuss homework problems with other students. However, each student must write up the homework individually in his/her own words, rather than merely copying someone else's.


There will be one midterm in class on Thursday October 28. The final exam is scheduled for December 16 between 5:15pm and 7:45 pm, and will be held in our classroom Javits 101.

Make certain that you will be available at these times, as there will be no scheduled make-ups for these tests.

Please note that makeup exams are only given if a student misses an exam for unforseeable circumstances beyond the student's control. In particular, schedule conflicts (such as other exams, or plane flights) are not an acceptable reason for missing an exam.


The midterm for mat 310 will take place in class on Thursday 10/28/10. The questions on the midterm will deal with the topics covered in sections 1.1-1.6,2.1-2.5,2.7,3.1-3.2. In preparing for the midterm you should review each of the main definitions and the statements of the main theorems given in the text. Also you should try to work out the problems in the review sheet for the course midterm.

The review sheet for the course midterm (with many solutions given) can be found at review for midterm .

Results of Midterm

Your midterm grades have been posted on Blackboard. The class average is 64%. Following is the letter grade curve for the midterm: A>84%; B>64%; C>50%; D>39%.

The solutions to the midterm problems can be found at solutions for midterm problems .

Final Exam

The final exam is on Thursday 12/16/10 from 5:15pm to 7:45pm in our classroom Javits 101.

Topics on the final exam will be taken from the following sections of our text book: 3.3-3.4,4.1-4.4,5.1-5.2,5.4,7.1.

A review sheet for the final exam can be found at review problems for final .
