Highlights
The diagram that made me Wikipedia-famous(-ish)!
A "trigonograph" is a diagram that illustrates a trigonometric principle, ideally making it obvious. The subject of this poster does this for the Angle-Sum Identities for Sine and Cosine.
It must work as intended, since someone posted my work to the Wikipedia "List of trigonometric identities" page: ( https://en.wikipedia.org/wiki/List_of_trigonometric_identities#Angle_sum_and_difference_identities ). Now it can be posted to your wall!
