Apparently, I never got around to posting solutions to your fifth problem set. Better late than never. Here are solutions to Problem Set 5.

# Final Exam Information and Resources

You have two options for taking the final exam: Tuesday, December 10th, from 3 to 5 p.m. or Friday, December 13th, from 12 to 2 p.m. Both offerings will be in our regular classroom.

The final exam will be comprehensive and will have a format similar to the midterms, with a mix of conceptually oriented multiple-choice questions and computationally oriented free-response questions. There will be no test corrections on this exam.

You're welcome (and, indeed, encouraged) to use Wolfram Alpha, your graphing calculator, or a similar tool on the exam. You're also welcome to bring two 3" x 5" index cards with notes (front and back).

Here's my office hour schedule for the next week:

- Friday the 6th, 2-3pm
- Monday the 9th, 10:30-11:30am and 2:30-3:30pm
- Tuesday the 10th, 10:30-11:30am
- Wednesday the 11th, 11:30-12:30pm
- Thursday the 12th, 2-3pm

And some resources for you as you study:

- Invertible Matrix Theorem (Unit 5 Version)
- Unit 1-4 Summary Chart
- All the Clicker Questions
- Math 194 Topic List
- Our Piazza Board

And some practice problems:

# Problem Set 9 Solutions

Here are some solutions to Problem Set 9. Let me know if you have any questions about them.

# Midterm 2 Information and Resources

Your second midterm will be Thursday, November 14th, during class. It will cover Unit 3 (Subspaces), Unit 4 (Linear Transformations), and Unit 5 (Eigenvalues and Eigenvectors).

You'll need to have access to some tool that can row reduce matrices, like Wolfram Alpha or certain graphing calculators. If you don't have access to such a tool, let me know as soon as possible. You'll also be allowed to bring one 3"x5" index card with notes (front and back).

Keep in mind that you'll have the chance to correct your midterm for up to 1/3 points back. If you score a 70 on the test, you'll be able to bring that up to an 80. I hope that takes the edge off your stress.

Here's my office hour schedule for the next week:

- Monday 10:30-11:30 (CFT)
- Tuesday 4:00-5:00 (CFT)
- Wednesday 4:00-5:00 (FGH 200)

Some resources for you to use as you study:

- Invertible Matrix Theorem (Unit 5 Version)
- Unit 1-4 Summary Chart (Complete)
- Unit 1-5 Clicker Questions

Below are a list of suggested practice problems from your textbook for you to work through as you study for the upcoming midterm. Note all of these problems have answers in the back of the book, unfortunately, but I would encourage you to ask and answer questions about these problems on our Piazza board.

- Section 2.1 #3, 4
- Section 3.2 #1, 2, 4, 11, 12, 14
- Section 3.4 #7, 10
- Section 3.6 #1-3, 6, 7, 9, 18, 22(a)
- Section 4.1 #4-6, 23
- Section 4.2 #2, 3, 5, 9, 10
- Section 6.1 #1, 3, 7(a), 8, 26

# Solutions to Problem Sets 7 and 8

As promised, solutions to Problem Set 7 and solutions to Problem Set 8.

# Problem Set 9, Due November 7th

Here is Problem Set 9, due at the beginning of class on Thursday, November 7th. You may find the Wolfram Demonstration "Eigenvectors in 2D" useful for one of the problems.

Also, here's my office hour schedule for the week:

- Monday 10:30-11:30
- Tuesday 4:00-5:00
- Wednesday 11:30-12:00

All office hours will be held at my Center for Teaching office.

# Application Project

Here's all the information you need to know about the application project. Note that proposals are due Tuesday, November 12th.

# Problem Set 8, Due Thursday, October 31st

Here's Problem Set 8, due at the start of class on Thursday, October 31st. Please note that I won't have any office hours this week, as I'm out of town, but you're welcome to email or tweet me with your questions.

# Problem Set 6 Solutions

Here are (corrected) solutions to Problem Set 6.

# Problem Set 7, Due Thursday, October 24th

Here's your seventh problem set, due at the start of class on Thursday, October 24th. **Update: **Please skip question 7. We didn't get to that material in class today.
