I am trying to solve the following equation:

1/f^.5=-2.0*Log(e/d/3.7+2.51/(Re*f^.5))

Given Re, e, d, can the Ti-89/92 solve this for f?  I have tried using solve()
and zeros().  Solve() just tries to rearange the equation for f (not
possible).  Zeros didn't seem to work either.

BTW, this is the Colebrook eqn, if you are wondering.

Thanks,

Mark
