4.3-4.4, due on May 13

(difficult)
The proof of theorem 4.11 seemed difficult (even though it's analogous to a theorem in ch 1). It seems like the difficulty of the proofs increased in this section.

(reflective)
I thought the method of dividing f by (x-a) to find f(a) (in 4.4) was very interesting. I suppose we may use this property again when we talk about more general rings.
