Trigonometry - Half-Angle Identities

This video covers Half-Angle Identities, even though the board says Double-Angle. The Commander-in-TEACH returns for another term, to cover these trigonometric identities and simplify trig expressions. We do half-angle identities for all of the trig functions, including sin, cos, and tan. Wave the flag for math, and YAY MATH!
