Explanation Given information: R n ( x ) be the n th remainder of f ( x ) = cos x at x = 0 . lim n → ∞ | x | n + 1 ( n + 1 ) ! = 0 Formula used: 1) lim n → ∞ | x | n + 1 ( n + 1 ) ! = 0 2) The reminder formula is, R n ( x ) = f ( n + 1 ) ( c ) ( n + 1 ) ! ( x − a ) ( n + 1 ) . where c is a number between a and x Proof: f ( x ) = cos x Differentiate with respect to x , f ' ( x ) = − sin x Differentiate with respect to x , f ' ' ( x ) = − cos x Differentiate with respect to x , f ' ' ' ( x ) = − ( − sin x ) = sin x . Differentiate n th times with respect to x , f n ( x ) = { | sin x | n is o d d | cos x | n is e v e n Differentiate ( n + 1 ) t h times with respect to x , f n + 1 ( x ) = { | sin x | n is even | cos x | n is odd The function f ( x ) = cos x can be differentiated n + 1 times on an interval containing the number a = 0 . Then for each x in this interval, there exist a number c between 0 and x such that, | R n ( x ) | = { | cos x | ( n + 1 ) ! | x | ( n + 1 ) n is even | sin x | ( n + 1 ) ! | x | ( n + 1 ) n is odd Usually the precise value of c is unknown

Question

Chapter 11.5, Problem 45E

To determine

To prove: For any fixed value of x, |Rn(x)| ≤ |x|n + 1(n + 1)! and hence conclude |Rn(x)| → 0 as n → ∞. This shows that the Taylor series for cos x converges to cos x for every value of x.

Where, Rn(x) be the n th remainder of f(x) = cos x at x = 0.
