Math 231

Here are the solutions to Wednesday's exam. I haven't graded them yet but I'll post the scores when I do. Have a great break and see when classes resume.

Here are the solutions to the 2019 exam. And here are the extra problems from class today, and here are their solutions.

Here are the solutions to Quiz 4. I'll return these quizzes in class today.

Sorry, the link to the 2019 exam was broken. I've fixed it now.

Some more details about the exam coming up on Wednesday, April 17th:

• The exam will cover everything up to and including Section 4.7.
• You can use any calculator, graphing, scientific, whatever. You cannot use a computer or a phone, even if you have a calculator app on your phone and promise to only use it. No exceptions, sorry. None of the problems will specifically require a calculator, since exact answers are preferred anyhow.
• You may bring to the exam a one-page, two-sided sheet of notes in your own handwriting. I want it to be written in your own handwriting because the process of making a notesheet is helpful for studying, and I don't want people downloading or xeroxing someone else's notesheet. Also I want to avoid weird tiny print, magnifying glass scenarios with typed sheets.
• Please don't use the bathroom, etc., during the exam. This is not an absolute prohibition, since I realize sometimes life compels people to leave the room in some way. I don't like imposing this policy, because I think it's disrespectful to you students, but in recent semesters I've had problems with people exchanging answers in creative ways in bathrooms, and I don't want to have an atmosphere where students do that.

Here is a model exam to help you study for next week's midterm. More information on that coming soon.

I'm on my way to office hours but am late. My apologies, I was dealing with some health issues of my parents'. I will probably not be there until 1:45 or so.

There will be a solar eclipse during class on Monday, peaking at 3:25pm. If you can get yourself safe eclipse-watching glasses (I think many public libraries are distributing them), I encourage you to bring them.
