Hello ! Use " = " instead of " := " . And use Normal ! flt[x_] = Normal[Series[f1[x], {x, 0, 10}]] Meilleures salutations F.Jaccard -----Message d'origine----- De : Xiaolei Li [mailto:xli10 at uiuc.edu] Envoyé : vendredi, 14. mai 2004 06:12 À : mathgroup at smc.vnet.net Objet : [mg48114] Maclaurin Series hi, i have some function defined in f1. i'd like to define a new function, f1t, that is the Maclaurin expansion of f1. when i do something like: Series[f1[x], {x, 0, 10}] it gives me the correct expansion. but how do i define f1t? i tried: f1t[x_] := Series[f1[x], {x, 0, 10}] that doesn't work because it evaluates f1[x] before giving it to Series[]. i also tried something like: f1t[x_] := Evaluate[ Series[f1[x], {x, 0, 10}] ] but that didn't work either. i'm a mathematica n00b. any help is greatly appreciated. thx. -- Xiaolei Li | xli10 at uiuc.edu | www.xiaolei.org
