Hello !
Use " = " instead of " := " .
And use Normal !
flt[x_] = Normal[Series[f1[x], {x, 0, 10}]]

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.
