Due on gradescope on Jan 28 6pm.

0. Join our discord server, and setup your own homepage in the Math 104, Students Area.

1. Try these exercises Ross 1.10, 1.12, 2.1, 2.2, 2.7, 3.6, 4.11, 4.14, 7.5

Try not to look up the solutions. And write up the argument in your own way, and try to be clear make your writing easy to follow. It is OK that you don't completely solve the problems, but do try to give each some thoughts.

As I mentioned in class today, some of the problems are easy/obvious when you see them, but not so easy when you try to write down a proof. As Francis Bacon said, 'talking makes one sharp, writing makes one precise', so do try to do both talking and writing.

Please submit upload your solution to discord by next Wednesday, and submit to gradescope by next Friday.

I'd like to hear your feedback and suggestions about the class, do you want it to be more formal and rigorous? Do you think the in-class discussion is helpful? As I am also new to this approach, any suggestions would be helpful. You can leave comment on your homepage, or message me on discord or email.
