Few (legitimate) tutors will complete students assignments for them. Sorry.

A better method for obtaining assistance might be to pick one representative exercise, and show how far you can get. Then the tutors can see where you are stuck, and can provide you with useful advice.

Are you saying that you are needing instruction on this topic...?

We'll be glad to provide you with links to appropriate online resources, but we cannot replace your classroom instruction within this environment. So please specify if this is what you are requesting.

Thank you.
