Newton's Method is a very elementary technique, and I strongly recommend you try to learn about it and how it works.

If you learn what Newtons Method is and need tutoring with Matlab, you are in the right place! I volunteer to help you! Tell me what is causing you trouble.

If you need tutoring with Newtons Method though.. I think you are on the wrong site :-/

Especially if this is for a homework assignment

Thank you, Firstly, what is the purpose of this method? which is used in cases?

[Andrew Reibold]

Newtons method is a method for finding successively better approximations to the roots (or zeroes) of a real-valued function

But I'd rather be helping you with the Matlab stuff than the Newtons method stuff... :-(
