This tutorial explains clearly and intuitively what "pi" is, and how the radian angle measurement system works using the intrinsic properties of all circles. Students learn the natural advantages of this system in simplifying math formulas. The tutorial ends with two example problems computing arc length of angular displacements in both revolutions and degrees.

This study aid connects four types of descriptions (Verbal, X-t graphs, V-t graphs, and Motion Maps) to various scenarios involving Uniform Accelerated Motion (UAM). Because the same motion is described in parallel in several different graphical "languages", it is likened to the Rosetta Stone, a key archeological discovery that unlocked the secrets of ancient Egyptian hieroglyphs.
