Table of values for the trigonometry functions sine, cosine, tangent, cosecant, secant, and cotangent based on the degrees and radians found on the unit circle. Unlike most of the tables on the Internet, this table is complete, nicely formatted, and easy on the eyes.
In pre-calculus, the unit circle is sort of like unit streets, it’s the very small circle on a graph that encompasses the coordinates. It has a radius of hence the unit. The figure here shows all the measurements of the unit circle:
Unit circle not using paper. Looking forward to getting to unit circles so I can do this!
Graphs from the Unit Circle: In this lesson, students use uncooked spaghetti to transfer lengths from the unit circle to a function graph on large butcher paper. In the process, they discover the key features of sine and cosine graphs. The activity is presented for students working in degrees, but another version of the handouts is provided for students working in radians.
