The lower determination of the $\displaystyle \frac{25 \pi}{6}$ is:
a) $\displaystyle \frac{\pi}{6}$
b) $\displaystyle \frac{\pi}{3}$
c) $\displaystyle \frac{2\pi}{3}$
d) $\displaystyle \frac{3\pi}{5}$
e) None of previous
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.
$\displaystyle \frac{25 \pi}{6}=\frac{24 \pi}{6}+\frac{\pi}{6}=4 \pi + \frac{\pi}{6}$
