Interactive video lesson plan for: Euler's formula with introductory group theory

Activity overview:

How some perspectives from group theory shed light on a way the formula e^(pi i) = -1 can make intuitive sense.

There's a slight mistake at 13:33, where the angle should be arctan(1/2) = 26.565 degrees, not 30 degrees. Arg! If anyone asks, I was just...er...rounding to the nearest 10's.

For those looking to read more into group theory, I'm a fan of Keith Conrads expository papers: http://www.math.uconn.edu/~kconrad/blurbs/
