Could you show the missing pieces here? Why is 5/n! Greater then 5sin^2n/n!

**11. Use the direct comparison test to show that the series ∑ (from n=1 to ∞) (5 sin² n / n!) converges.**

We observe that:

\[
\frac{5 \sin^2 n}{n!} \leq \frac{5}{n!}
\]

The series:

\[
\sum_{n=1}^{\infty} \frac{5}{n!}
\]

converges, so the series:

\[
\sum_{n=1}^{\infty} \frac{5 \sin^2 n}{n!}
\]

also converges as well.
