CERCLE: trigonometry question, HELP PLZZ

Answer 1

In a circle, if \[6\theta = 3\pi + 2k \pi \]
Then
\[\theta =\pi/2 + k\pi/3\\ or \\\\\theta=\pi/2 + 2k\pi \]

Answer 2

divide everything by 6 and you get the first answer

Answer 3

yea, but i mean doesn't 2*k*pi means we got around in a circle and come back again?
so isn't it should be the second one?
