Example 12. (a) Find the Taylor polynomial of degree n = 5 for , expanded about .

First, find the derivatives of f(x).

Second, evaluate the derivatives of f(x) at x = 2, and obtain a sequence of constants .

Third, substitute the constants in Taylor's formula.

Example 12. (b) Find the Taylor polynomial of degree n = 9.
