2. Suppose you want to approximate sin x with the sixth-order Maclaurin series:

\[
\sin x \approx x - \frac{x^3}{3!} + \frac{x^5}{5!} - \frac{x^7}{7!} + \cdots
\]

Which of the following calculations would produce the most truncation error?

a. \( \sin \frac{\pi}{10} \)

b. \( \sin \frac{\pi}{2} \)

c. \( \sin \pi \)

d. \( \sin 2\pi \)

e. They would all have equal error for a sixth-order series.
