On Monday we will have the talk by Ruth Cervantes and Lauren Mish, on Problems 3-18 and 3-19 from chapter 3. but they bought the old book, so it isn’t the same.
The problems they will be working are here. Ch 3 Questions for Talk
I suggest you read and try to solve them. the questions I had suggested were 3-21 and 3-22 from the 4th edition. You could try to work them also.
We will spend most of this week on chapter 4. I am looking for a team of two to speak on Friday, doing a couple of problems from the end of chapter 4. If I do not get a volunteer team by email this weekend, I will select a team on Monday at the start of class.
