If `2cos 3theta=1`, then the value of `theta` is

If (1-cos2 theta)/(1+cos2 theta)=3, then the general value of theta is

If sin alpha=(1)/(2) and cos theta=(1)/(3), then the values of alpha+theta (if theta,alpha are both acute) will lie in the interval

If sin alpha=(1)/(2) and cos theta=(1)/(3) then the values of alpha+theta( if theta,alpha are both acute angles) will lie in the interval

If 2cos theta+sin theta=1 then the value of 4cos theta+3sin theta is

If 3cos theta=1, find the value of (6sin^(2)theta+tan^(2)theta)/(4cos theta)

if 5cot theta=4, then the value of ((5sin theta-3cos theta)/(sin theta+2cos theta))
