WebDec 3, 2016 · Putting together ( 3) − ( 5), we find that f ( n) ( 0) = 0 for all n and we are done! NOTE: The function f ( x) = e − 1 / x 2 for x ≠ 0 and f ( 0) = 0 is C ∞. But its Taylor series is 0 and therefore does not represent f ( x) anywhere. So, the assumption that f ( x) can be represented by its Taylor series was a key here. Share Cite
