8.5, Due April 11th 2016

1) One of the most confusing parts to me while reading was how they were trying to complete the table on page 280.  Also for me, the most difficult groups we have studied are the dihedral groups and I had a hard time following the last half of the proof of Theorem 8.32.
2)  We were basically exploring theorem 8.30 before right?  I also love the chart on 281... it is very helpful to break it down in order to understand basically what each group is isomorphic to and why.  I feel like it is a good way to conclude our exploration of groups.


For the test:

  • Which topics and theorems do you think are important out of those we have studied?
As far as MOST IMPORTANT, I think it is the ones that you asked us to know how to prove on the previous midterm exams.  And just knowing the characteristics of groups and rings.
  • What do you need to work on understanding better before the exam? Come up with a mathematical question you would like to see answered or a problem you would like to see worked out.
I need to work on this last stuff that we have been studying.  I definitely feel like it is the most difficult.  I feel like my understanding is about 2 feet deep in a 20 foot pool!
 
#23 in 8.2 in the second edition.  Unless you feel like this won't help us that much with understanding this latter material.  I am not really sure what problems will help me to gain a better understanding for the final.

  • What have you learned in this course? How might these things be useful to you in the future?
I think this class has really taught me how to prove something logically (identify my end goal, use the info given in the assumptions to get there, create a strategy, and go).  I am so grateful for this, because I don't fear proofs like I used to.  It makes me feel a little more comfortable and ok with the idea of theory of analysis in the fall.  When we studied rings, I felt like I better understood basic characteristics of the different sets that we work in and the reasons why things work or don't work in algebra - I feel like that is definitely something that I can use as a teacher.
