Hi Jason, Unprotect[Conjugate]; Conjugate /: Conjugate[BesselJ[n_, x_]] = BesselJ[n, Conjugate[x]]; Protect[Conjugate]; results in: In[4]:=Conjugate[BesselJ[1, 1 + I]] Out[4]=BesselJ[1, 1 - I] Peter "Jason Sidabras" <jsidabra at mcw.edu> schrieb im Newsbeitrag news:bkedf9$m4s$1 at smc.vnet.net... > Hello, > > I am currently running into a small hang-up that I was hoping someone would > be able to help me with.
