Angular Velocity

The handbook gives average and instantaneous angular velocity from angular displacement.

Average angular velocity

\omega_{av}=\frac{\theta_2-\theta_1}{t_2-t_1}=\frac{\Delta\theta}{\Delta t}

Instantaneous angular velocity

\omega=\frac{d\theta}{dt}

angular displacement

$\theta$
