time (not x). The slope of this line will give the angular velocity (ω)and I can use that with the following relationship: With an angular velocity of 0.02328 radians per second, I get a ground ...

The frequency tells us how many “full circles” the signal will make in a second. Another way to say that is radians per second, which I’ll explain in depth in just a moment. The phase shift ...

If you think of frequency in Hertz as cycles per second, all the 2π you find in these equations convert Hz to “radian frequency” since one cycle per second is really 360 degrees of the sine ...
