f (n) (0) To show that a function f(x) is equal to its Taylor Series E x" at some n! n=0 TO ER, f () (0) a) it suffices to show that x converges at co. n! n=0 f (n ) (0 ) b) it suffices to show that x converges absolutely at co. n! n=0 c) it suffices to show that lim Rn.o(x0) = 0. n-too d) f(x) is always equal to f ( n ) (0 ) x for all r E R. n! n=0 e) None of the above
