Angular frequency precession of spinning top

[indie452]

Homework Statement

im doing a sipnnig top question and i have got an answer for the precession angular velocity
this site shows a good example of what i did: http://hyperphysics.phy-astr.gsu.edu/hbase/top.html

and so i have gr/K²w if i sub in I=mK²

but i need to find the angular frequency of the precession. I'm confused between the angular velocity and frequency and how to change between the two.

any help appreciated

I'm confused between the angular velocity and frequency and how to change between the two.

ω is measured in radians per second. How many radians in one cycle?

so i can just use w=2pif?

Sure.

ok but i was discussing this problem with someone today and they said that (gr)/(K^2*w) is the angular frequency and now I'm even more confused is this the angular frequency of precession or is it (gr)/(K^2*w*2pi)

Yes, the first expression is the angular frequency (also called angular speed) measured in radians per second. (If you wanted just the frequency f, in cycles per second, use ω = 2πf.)

Sorry if I wasn't clearer before.

ok i get it now thanks for that :)
