Three of the easy problems are completed now.

We have six problems total. I solved two last week or the week before. Today I solved another three problems. Except that one of these three has a second part. I also did not use interals but instead argued my points to get to the answers. I did though use some intergrals today. I also used my table of integrals book to help me with the binomial expansion. But I don't think I need it. So really at this point I am proof reading solutions and preparing to typeset some work on the third part of the last problem. I also need do the fourth part and then I have a second part of another problem to solve and I am done. I am up all night and another student might call me to talk about the home work overnight.
