Does anyone know how to tell Mathematica 3 that the resulting funktion f
has to go trough a certain point? I can not change my function, since
it is a physical modell. That is the coefficients have to be found the
way, that my conditions are met even if it is not the best fit. I could
not find any options in the manual.

un = Function[{x, n}, (1-x/c)^(n+0.5)]; f = Fit[werte, Table[un[x, n],
{n, 0, 2}], x];

Thanks, Sergio
