$sqrt(1-sin^2 theta)/(3 sin theta$

Take note first that

$cot theta=cos theta/sin theta$

and

$cos^2 theta=1-sin^2theta$

and

$cos theta=sqrt(1-sin^2theta)$

$cot theta/3=1/3*cos theta/sin theta= sqrt(1-sin^2 theta)/(3 sin theta$

it is now in terms of $sin theta$

Have a nice day !!! from the Philippines.
