Expert Solution

Step 1

The given function is $f (x) = \sin x$ .

Calculate the Taylor polynomials $T_{2} (x) and T_{3} (x)$ at $a = 0$ and $a = \frac{π}{2}$ .

Taylor polynomial is given as $T_{n} (x) = \sum [\frac{f^{n} (a)}{n!}] \times {(x - a)}^{n}$ , where n ranges from 0 to ∞ and a is the value at which polynomial function is to be determined.

^{$\begin{array}{rcl} T_{2} (x) & = & \frac{f (a)}{0!} {(x - a)}^{0} + \frac{f' (a)}{1!} {(x - a)}^{1} + \frac{f'' (a)}{2!} {(x - a)}^{2} \\ = & f (a) + f' (a) (x - a) + \frac{f'' (a)}{2} {(x - a)}^{2} \end{array}$}

$\begin{array}{rcl} T_{3} (x) & = & \frac{f (a)}{0!} {(x - a)}^{0} + \frac{f' (a)}{1!} {(x - a)}^{1} + \frac{f'' (a)}{2!} {(x - a)}^{2} + \frac{f''' (a)}{3!} {(x - a)}^{3} \\ = & f (a) + f' (a) (x - a) + \frac{f'' (a)}{2} {(x - a)}^{2} + \frac{f''' (a)}{6} {(x - a)}^{3} \end{array}$
