Degrees are not the only units we use to measure angles. We also use radians. Just as there are \(360^\circ\) in a circle, there are \(2\pi\) radians in a circle. Compute \(\sin \frac{\pi}{6}\), where the angle \(\frac{\pi}{6}\) is in radians.
pi/6 x 360o/2pi = 300 pi/6 is 300 sin pi/6 = sin 30 = 1/2
