# Power of sine!

**Calculus**Level 5

\[I(n)= \int _{ 0 }^{ \frac { \pi }{ 2 } }{ \sin ^{ 2n }{ x } } \ dx \qquad \qquad X=\sum _{ r=1 }^{ \infty }{ \frac { I(r) }{ { \left( \begin{matrix} 2r \\r \end{matrix} \right) } } } \]

Given the above, find \(\left\lfloor { 10 }^{ 4 }X \right\rfloor \)

**Notation:**

- \( \displaystyle \binom{n}{m} = \frac{n!}{n! (n-m)!} \) denotes the binomial coefficient.
- \(\lfloor \cdot \rfloor\) denotes the floor function.
