If you opted not to do Problem 2(B), then you should do that problem at some point as well; you don’t need to submit Problem 2. 13 March Exercise 3.2.4, along with the rest of section 3.2, should also be completed before Spring Break. 13 March Here are the exercises for Section 3.3 and Section 3.4.
