#### Answer

$\dfrac{\pi}{6} + n(2\pi)$

#### Work Step by Step

RECALL:
The angles cotermnal with $\theta$ can be found using the formula $\theta_1=\theta + n(2\pi)$, where $n$ is an integer
Thus, an expression that will give an angle coterminal with $\frac{\pi}{6}$ radian is:
$\dfrac{\pi}{6} + n(2\pi)$
