Toy top precession

    Caption: A diagram illustrating the precession of a toy top.

    Note:
    1. L is angular momentum of the toy top's rotation on its axis of rotation.
    2. ω_s is the angular frequency of the toy top's rotation on its axis of rotation.
    3. ω_p is the angular frequency of the toy top's precession around the vertical direction.
