To elaborate a bit: that works because sin(x) is very close to x for small x, but only when x is measured in radians.

- shadowgovt 4y agoThat's because of the equality relationship between 2π radians and the length of the unit circle perimeter. If one is working with a sine taking in turns, one can just adjust by saying sin(q) ≈ 2π * q for small q.
