Integral 21

Calculus Level 4

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

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.
