In Response To 'Re: Abs of a complex number' --------- Ok Thanks but how about the Abs??? In: ComplexExpand[Abs[1/(1 + I*w)]] Out: 1/Abs[1 + I w] ----- In: Abs[1/(1 + I*w)] Out: 1/Abs[1 + I w] --- In: Abs[ComplexExpand[1/(1 + I*w)]] Out: Abs[1/(1 + w^2) - (I w)/(1 + w^2)] :-( I dont get why he cant do that...
