1) You have submitted this question two times.

2) There are many parts to this question. I would presume that there have been some similar problems in your class lectures and book. The questions are rather straightforward.

3) What have you done, so far, in attempting to do them yourself? If you would point out any particular stumbling block, I would like to help, but I don't think I should do all of your homework.
