text: Since the precession rate is proportional to the torque, and the torque due to gravity acting on the center of mass is proportional to the distance perpendicular to the gravity vector between the center of mass and the support point, and that perpendicular distance is proportional to the sine of the nutation angle, then the precession rate is proportional to the sine of the nutation angle and the period of precession is inversely proportional to the sine of the nutation angle.
