QUESTION:

Let \(T_{n}\) be the nth Taylor polynomial at x = a for a polynomial f of degree n. Based on the result of Exercise 53, guess the value of \(\left|f(x)-T_{n}(x)\right|\). Prove that your guess is correct using the error bound.

ANSWER:

Step 1 of 3

The Taylor polynomial \(T_{n}(x)\) of a polynomial f of degree  is exactly equal to f. It just might look different if not centered at 0 , but if you were to simplify it would become the exact same.

So then the error bound must be \(0\)

\(\left|f(x)-T_{n}(x)\right|=0\)
