11.10 Taylor and Maclaurin Series 1. Taylor and Maclaurin Series Question Which functions have power series representations? How can we Fnd such representations? Suppose f is a function that can be represented by a power series f ( x )= c 0 + c 1 ( x - a )+ c 2 ( x - a ) 2 + c 3 ( x - a ) 3 + ... What are the coefficients c n in terms of f ? Theorem 1.1. If f has the power series representation at a , that is, if f ( x )= ± n =0 c n ( x - a ) n , | x - a | <R then its coefficients are given by the formula c n = f ( n ) ( a ) n ! 1

Section 11.10 Taylor and Maclaurin Series 2 Defnition 1.1. The Taylor Series of a function f centered at a is the power series expansion of f ( x ) about a and is in the form f ( x )= ± n =0 f ( n ) ( a ) n ! ( x - a ) n = f ( a )+ f ± ( a ) 1! ( x - a )+ f ±± ( a ) 2! ( x - a ) 2 + f ±±± ( a ) 3! ( x - a ) 3 + ··· Defnition 1.2. The Maclaurin Series of a function f is the power series expansion of f ( x ) about 0 and is in the form f ( x )= ± n =0 f ( n ) (0)
