Both, David's and Bobby's (without beep) solutions work perfectly for me too. The David's plot looks pretty illustrative. $Version: "8.0.1.0 for Microsoft Windows (64-bit) (February 23, 2011)" -----Mensaje original----- De: DrMajorBob [mailto:btreat1 at austin.rr.com] Enviado el: mi=E9rcoles, 02 de noviembre de 2011 12:22 Para: mathgroup at smc.vnet.net Asunto: Re: Simple question about inverse of a function It works perfectly here (with an error beep you can ignore), and this does the same... without the beep: Clear[f, g] f[theta_][t_] := (1 - t)^theta g[theta_] = Quiet@InverseFunction[f[theta]] 1 - #1^(1/theta) & $Version "8.0 for Mac OS X x86 (64-bit) (October 5, 2011)" Bobby On Tue, 01 Nov 2011 00:01:55 -0500, Mikael <mikaen.anderson.1969 at gmail.com> wrote: > Thanks David for your reply but unfortunately the solution does not > work for me.
