# Integral 21

Calculus Level 5

$\displaystyle \int_{0}^{\pi} \dfrac{1-\cos x}{x} \, dx$

If the above integral equals $V$, find $\left \lfloor 10^5 V \right \rfloor$.

NB: Once you figure out the integral's closed form, perhaps with a bit of research, you can use Wolfram Alpha to help you get the final form.
