Activity Overview

How does the magical black box produce values for sin(x)? Something as simple as a quadratic function can produce values for sin(x) with remarkable accuracy. Increase the degree of this polynomial slightly and the results are really impressive. This activity involves simple applications of the factor theorem, differential calculus and is a great launching point for the mean value theorem.
