Six Trigs in 60 Seconds!

In this video, we show a single diagram consisting of various triangles that connects the six primary trig functions (sine, cosine, tangent, secant, cosecant, and cotangent) to lengths of line segments created from the unit circle (circle of radius 1). We also briefly discuss the fact that the "co" on three of the functions refer to the "complementary angle."
