Trigger is your trigonometry cheat sheet! Interpreting the six standard trig values as lengths of segments, Trigger encapsulates almost everything you need to remember about those values, in an intuitive form. Segments shrink to nothingness or stretch out to infinity, making the nature of individual values clear; segments also combine to form numerous similar right triangles, revealing many relationships among the values as simple geometric properties. For complete information, Trigger links to a highly detailed document discussing of the wealth of information to be found in the figure.
