People aren't going to do your homework for you. Surely if you've been given this to do, you must have learnt something in the class you're taking, or given books to read, etc?

Of course! You're asking us to do your homework. That's really a bad idea! How are you supposed to learn something if someone does the job for you? If you have some doubt about one or more topics, feel free to ask but at least show what you've done by yourself and do a more specific question.
