Homework Help Rules

 

A simple reminder to all: this is the "Homework Help" forum, not the "Homework Answers" forum. We will not do your work for you, only point you in the right direction. Posts that do give the answers may be removed.

 

So poloka could you show where you have got to and what has stopped your progress - hopefully members can then help you to overcome your difficulties yourself.
