    Three little known equalities:

    From Smirnov:
    [tex] \theta_{\mbox{sun}} + \theta_{\mbox{cabibbo}} = {\pi \over 4} [/tex]

    From De Vries:
    [tex] \ln {m_\tau \over m_\mu} = \pi - {1 \over \pi} [/tex]

    From Smirnov again:
    [tex] \sqrt {m_\mu \over m_\tau} \sim \sin \theta_{\mbox{Cab.} } [/tex]

    Can anyone predict them?

    de Vries has a secondary formula for the electron-muon relationship, namely
    ln(mu/me) / (2pi-3/pi) = 1.000627.

    In principle one could recast them in terms of hyperbolic cosines and sines, for instance 1pi-1/pi= 2 sinh(ln(pi)) but it does not clarify the situation.

    For instance, taking logarithms we have

    [tex]\ln (\sin \theta_C) \sim - \sinh (\ln \pi)[/tex]
