    Hi Apprentice,

    I'm not sure what lower determination means, but $\displaystyle \frac {25 \pi}{6}$ amounts to 2 full $\displaystyle 2 \pi$ revolutions plus $\displaystyle \frac{\pi}{6}$ radians more.

    So, I would guess that $\displaystyle \frac{\pi}{6}$ is the one you need.

    $\displaystyle \frac{25 \pi}{6}=\frac{24 \pi}{6}+\frac{\pi}{6}=4 \pi + \frac{\pi}{6}$
