This topic has been surprisingly neglected in the research literature. For example, our search of recent ATCM conferences revealed no work at all focusing on school trigonometry. Even the wider research literature contains very few references to teaching and learning trigonometry. Trig functions take an angle and return a percentage. $\sin(30) = .5$ means a 30-degree angle is 50% of the max height. The inverse trig functions let us work backwards, and are written $\sin^{-1}$ or $\arcsin$ (вЂњarcsineвЂќ), and often written asin in various programming languages.
