ABSTRACT
Most concepts that economists are concerned with are quantitative in nature. Therefore, much of economic analysis is invariably mathematical in nature. To express relationships between economic variables, economists employ various mathematical functions. The previous chapter introduced the reader to the set of polynomial functions. The first section of this chapter focuses on various types of power functions. The following two sections explore finite and infinite sequences and series, and offer some rules of summation. Economics students will utilize this knowledge in their econometrics and time-series analysis courses.
