I studied derivatives before, but kind of forgot them all, is there a website that gives me an overview of derivatives. What is first and second derivatives, how to find it, all the derivative rules and so on... thank you

Have you considered a Calculus Text? Even a review/study guide? Schuam's College Outline Series, College Calculus is very good. It is available at Barnes Noble.
