Rest of Section 6.2, Due February 22

Part I: What was the most difficult part of the material for you?

 I am most confused about the proof in theorem 6.11. The second part of the proof is assuming that f is injective where f:R to S and f is a homomorphism of rings with kernal K, and we are trying to prove that K = (0subR). I can understand most of it until they say that f(c)=0sub s and that f(c)=f(0subR). I do not know why f(c)=f(0subR). I kept trying to look at how the kernel fits into this equation and I am just getting really lost at this point.


Part II: Write something reflective about the reading.  


This section is really becoming more and more abstract. I am having such a hard time with making a connection with some of this stuff to things we have already done, but maybe there are no connections to really make yet from past things I have done. I just hope that working on the homework and seeing other example will help me understand what some of these theorems are even saying.
