d = 3 tan 2πt,
where t is the time measured in seconds since the beacon started rotating. Solve the equation for t.
-------
tan(2pit) = d/3
------
2*pi*t = invtan(d/3)
-------
t = (1/(2pi))*invtan(d/3)

It seems to me that the problem in whole doesn't make sense.
There is no connection between the formula and rotating beacon. (and rotating at all).
