Hello !

Use " = " instead of " := " .
And use Normal !

flt[x_] = Normal[Series[f1[x], {x, 0, 10}]]

Objet : [mg48114] Maclaurin Series


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.
