Question
a. Approximate the given quantities using Taylor polynomials with $n=3$.b. Compute the absolute error in the approximation assuming the exact value is given by a calculator.$$\cos (-0.2)$$
Step 1
The Taylor polynomial of degree 3 is given by: $$p_{3}(x)=f(0)+f'(0)x+\frac{f''(0)x^{2}}{2!}+\frac{f'''(0)x^{3}}{3!}$$ where $f'(x)$, $f''(x)$, and $f'''(x)$ are the first, second, and third derivatives of $f(x)$, respectively. Show more…
