    As this is still unanswered, I'll indicate how I think it would be done.

    You use triangles and trigonometry to show how distance C is related to distance B, where C is the height of point C above the horizontal line passing through O, and B is the distance of point B from a vertical axis through O.

    Once you have C related to B, differentiate twice wrt time, to obtain d²C/dt² in terms of dB/dt, etc.
