Matrices on TI-89
Here's a pretty good page about doing linear algebra on the TI-89
The Final Exam will be Tuesday, May 5, 8:00-10:00AM in our usual classroom (CU 137). It will cover everything that we've discussed all semester. There will be an emphasis on material since the second exam: sections 3.5, pp.233-235 and pp.240-243 of section 3.7, 4.1-4.3, 5.1, and pp.375-378 of section 5.2. Calculators will be allowed, but the questions won't assume you have one.
You should review all of the homework problems and suggestions
for the first two exams. Here are a few
suggested problems for the sections I didn't assign homework for:
p.356 #11,13 [Note that the positive eigenvalue is called the "steady state growth rate"]
p.373 #1,3,5,7,9,17
p.384 #3,7,9,11,12
p.249 #63,65-67,70
Exam 2 was Wednesday, Mar 25.
It will be covering
sections 2.3, pp.106-113 of 2.4,
3.1-3.4, pp.189-192 of 3.5.
The questions will be like the following:
p.100 #22-31; p.115 #19,20; p.116 #23,24,27; p.150 #1-16; p.159 #5-8;
p.176 #1-10; p.177 #48-54,60-63; p.187 #1-12,27,28; p.207 #1-8.
Remember that any of those question types might be asked about
matrices mod p for some small prime p (like 2,3,5,7).
Calculators will be allowed, but the questions won't assume you have
one.
Exam 1 was during class on Friday, Feb 13.
It will
cover all of the material we've discussed so far using questions
similar to the homework problems. That is sections 1.1-1.4, 2.1, 2.2,
and spanning sets from 2.3 (pages 90-94).
In addition to studying the
problems from the first three homework sets, you might want
to look at:
p64 #33, 34
p83 #9, 10, 13, 17, 25, 28, 33, 35, 36, 40, 45, 53-57
p99 #3, 5, 6, 8, 12, 13, 15, 16
