# Preference of Angular frequency over frequency for sinusoidal graphs

 P: 4 Quote from 'The Physics of Vibrations and Waves by H.J.Pain': "However when we solve the equation of motion we shall find that the behaviour of x with time has a sinusoidal or cosinusoidal dependence, and it will prove more appropriate to consider not $\nu$, but the angular frequency $\omega$ = 2$\pi$$\nu$ so that the..." My question is, why are we prefering $\omega$ over $\nu$ just because of the fact that the graph will be sinusoidal/cosinusoidal? Does it make the calculations somehow easy, or has it got some other purpose?
 P: 4 so, according to you, we prefer $\nu$ over $\omega$. O.o but the book says that we prefer $\omega$ over $\nu$. $\omega$ contains 2$\pi$
