Kindly shut of the ALL CAPS, we don't like being yelled at.

Start with the definitions from your text book, if you're completely unsure.  Try to show us some of the math needed, and some of the formulas you know, or think might work.

Please read the forum rules.  We don't give complete step by step answers.  Most likely, your instructor did, in class.  So re-check your class notes.
