Homework to turn in when I collect: Section 1.6 #1, 8d,9d
Special Note: Students have asked for an earlier exam date. For the final exam, I will either give a take home on the
last day of class *or* have an examination that students may come and take upstairs at Lucas. This way a student may
wait until the exam date to take it or may take it early if he or she wishes.

Don't hesitate to stop by my office is you are having trouble. Also, be sure to check each time you present
to be sure I put your name here on the website. Tell me if I fail to list your name!

Presentation Homework for Tuesday: p22 #2 (anybody), p28 10-13
Homework to turn in when I collect: p27 #4, 7, 14
Next class anyone who can do #2 p22 can put it up -- you'll want to use Theorem 3.1. To help understand
the definitions for convergence and Cauchy sequences, I'll pass out a sequence of problems for presentation.
I'll prove theorems 4.1 and 4.2 (so read before hand to see what you understand and what you don't) and
that will finish Section 1.4.
Presentations: Rahavendra Kesari - eigenvalue problem, Chai Suryaneni #11 p14, Alys Rodriguez #2 p22 (revisit Thursday)
Presentation Homework for Tuesday: p22 #2 (Alys), p27 #3a, 9-13
Homework to turn in when I collect: p27 #4, 7, 14
Next class Alys will start with number 2 and I'll take volunteers on the homework on p27 since I have not discussed
that section yet. Then I will discuss the fundamental matrix a bit more, finishing out section 1.3 and start on
section 1.4.
Presentations: Alys Rodriguez 2, Vinay Gunugula 7c, Andrea Mullican 8c, Navena Palakala 9c
Presentation Homework for Tuesday: 1.2 #11 (Chai Suryaneni), eigenvalue probelem from 8.23.11, and 1.3 #2, 3, 4.
Homework to turn in when I collect: 1.3 # 6, 7, 8.
It seems everyone thought Thursday's class went too fast. After presentations on Tuesday, I'll work an example
that will help you understand all the properties of the fundamental matrix. Meanwhile, y
ou need to read each section before I present it to determine
what you understand and what you don't. You can always ask at the beginning of class about words or proofs you don't
understand. You'll probably need to read each section again after I present it. Feel free to ask
questions during class -- I love questions and would rather
move slower so that you understand than move fast when you do not understand. We are going to have fun this semester. I am
going to learn to pronounce Indian names and how to teach electrical engineers. You are going to learn some differential
equations and how to work well with a Texan who loves mathematics and teaching mathematics. We'll learn from each other.
Homework:
Read the syllabus. Read Chapter 1.1 - 1.3.
Presentation Homework for Thursday: 1.2 #2, 7c,8c,9c, 11.
Find all eigenvalues and eigenvectors for the matrix( (3,2,0), (2,0,0), (1,0,2) ).
Homework to turn in when I collect: 1.2 # 6, 7b, 7d, 8b, 8d, 9d, 10
I modify this page every class day. Sometimes I'll announce talks that you might want to attend.
I'll also use this page to record what presentations went on the board so you can see if
I give you credit. You'll present problems from the homework every day before I lecture -- I'll call on
you to put problems on the board.
