The Trigonometry of Sensed Angles -- An Analogue to the Ciruclar Functions.
Szabo, Steven
It is extremely difficult to extend in a natural way the concepts developed in high school geometry to motivate the concepts of trigonometry. To solve this difficultry, the author defines "sensed angles" as ordered pairs of rays and makes appropriate definitions which yield the familiar angle properties of plane geometry. He then shows how this definition also yields the familiar results of trigonometry. (Author/CT)
