You need to download a package of software written by VE3ERP.  I think it 
is now on the CQ website, called "Hamcalc".  While I don't have the 
formula handy, the program is easier and has dozens of good modules in it.

BTW--I'd not pay a lot of attention to coil calculations.  I'd put a cap in
parallel with the coil and find the resonant freq and calculate from 
there.  ARRL's "Lightning Calculator" handy for that, but if you don't 
have a "Dip" meter to read the resonance that won't work for you.  That 
method tends to take into account a lot more factors.
