This module provides the recourses to develop an interactive game that helps students learn the locations of the unit circle. Also, it provides an introduction to working with shift registers. Shift ...

We study strictly positive definite functions on the unit circle in the Euclidean space of dimension two. We develop several conditions pertaining to the determination of such functions. The major ...

This article compares two algorithms that compute values of the sine and cosine functions using analytic geometry and the unit circle definition of sine and cosine. One algorithm uses chords on the ...
