Find the vlaue of `theta` if `2cos3theta=1and0^(@)ltthetalt90^(@)`.

If (cos theta)/(1- sin theta) + (cos theta)/(1 + sin theta) =4 , then find the value of cos theta . Find theta if 0^(@) lt theta lt 90^(@)

If costheta=(5)/(13) , then find the value of tan^(2)theta+sec^(2)theta . 0^(@)ltthetalt90^(@)&tantheta=sqrt(6+sqrt(6+sqrt(6+....oo))) , then find the value of sec^(2)theta .

If sinthetaxxcostheta=(1)/(2) . The value of sintheta-costheta is where 0^(@)ltthetalt90^(@)

Solve : 2sin^(2)theta=(1)/(2),0^(@)ltthetalt90^(@) .

Solve : 2sin^(2)theta=(1)/(2),0^(@)ltthetalt90^(@) .

If sqrt(3) sin theta - cos theta = 0 and 0^(@) lt theta lt 90^(@) , find the value of theta .

If (cos^(2)theta)/(cot^(2)theta-cos^(2)theta)=3and0^(@)ltthetalt90^(@) , then find the value of theta .

If tanA=3/4, find the value of 1/sinA+1/cosA OR If sqrt(3)sintheta- costheta=0 and 0^(@)ltthetalt90^(@) ,find the value of theta

If sec(5theta-50^(@))=cosec(theta+32^(@)) , then the value of theta is: (0^(@)ltthetalt90^(@))

If (cosectheta+sintheta)/(cosectheta-sintheta)=(5)/(3) and 0^(@)ltthetalt90^(@) then what is the value of tan theta ?
