Hi,
if you dont't know what to do with x, you can bes
sure
that I also don't know it but if you miss the
x->any
rule you can add it with
Assuming[{c >= 0 && c <= 1},
f = Normal[Series[1 - c*ArcTan[x]/x, {x, 0, 2}]];
lst = x /. Solve[f == 0, x] // FullSimplify;
x -> # & /@ Select[lst, ! MatchQ[#, -1*_] &]
]
??
Regards
Jens
