Can you believe it? A mathematics review chapter in a signals and systems book! Well, yes, you saw it coming. Mathematics plays a starring role in the study of signals and systems, which is basically a discipline of applied math.

In this chapter, I cover the mathematical concepts that you need for studying signals and systems, including specific aspects of algebra, trigonometry, complex arithmetic, calculus, and polynomial roots. So grab what you need from this chapter, and come back as necessary when you're trying to decipher the core concepts of signals and systems. If you need a more rigorous review of mathematical tools than what I provide here, check out Calculus For Dummies (Wiley) and other For Dummies resources available at www.dummies.com.
