Re: -- Polynomial approximation for 1/(x+a) in large domain.

Hi
Thanks for the reply... I have one question, though. I haven't used
Maple before, so I wonder if I can do complex function approximation
(like say 1/(s+10) in terms of s, when s = j*w, w being real in [0,
50]). For that simple example of course, I can just manually split it
into real and imaginary parts and do two approximations, but for a
more complicated function, is there an easier method?
Thank you
Srikanth
