1. The connection between angle and time is what's known as angular velocity,
2. which we give this symbol ω--it looks sort of like a funny w.
3. In this quantity describes how quickly in radians we progress around this circle
4. and so it's units are in radians/second and the equation that describes this
5. is that the angle is equal to the ω*t--the angular velocity times the elapsed time.
6. I should put a Δ here. This is how much you've changed your angle.
7. So let's say we started an angle of 0 degrees, 0 radians were down here,
8. and I have an angular velocity--let's keep it simple of 1 radian/sec.
9. So what I want to know is how long will it take to complete one cycle
10. and you'll have to remember what one cycle means in radians when four cycle
