You might wish to discuss this with the instructor of the course for which this homework is required. After all, part of the purpose of taking a course is to learn the concepts. And the instructor and any teaching assistants are supposedly there to help you with this.

Alternatively, if you are trying to convince someone to do homework for you, you might want to contact someone that took the course previously so that you might have something in the form that the instructor wants. We likely can't help you with that.
