I have defined a function: ft(n,v)=Zeta(0,n+1,1-2*Pi*v*I)/Zeta(n+1) mag(n,v)=sqrt(ft(n,v)*conjugate(ft(n,v))) I want to find the points v at which mag(n,v)=0.5 (i.e. for n=2,3,4, etc.) Any of the so-called numerical solver techniques described in the help file with Maple simply return an expression containing the digamma function symbol (e.g. Psi) Any ideas? Thanks -Monty Wood
