You will find help more forthcoming if you don't just dump whole homework assignments for someone else to do.
Post a problem you are having trouble with, show where you get stuck, and you'll be surprised how much help you get.
After you do a few more similar problems on your own, post another kind of problem for more help.
Surely your textbook has solved problems just like the ones you are posting.
