if `tan((pi/2)-(theta/2)) = sqrt(3)` the value of `cos(theta)` is ?

If tan((pi)/(2)-(theta)/(2))=sqrt(3) , the value of sectheta is :

If tan((pi)/(2)-(theta)/(2))=sqrt(3) , then the value of costheta is.

If tan ((Pi)/(2) - (theta)/(2)) = sqrt3 , the value of cos theta is____

If (3 pi)/(2)

If theta in ((pi)/(2), (3pi)/(2)), then the value of sqrt(4 cos ^(4) theta + sin ^(2) 2 theta) + 4 cot theta cos ^(2) ((pi)/(4) +(theta)/(2)) is

If pi/2

If theta in ((pi)/(2), (3pi)/(2)), then the value of sqrt(4 cos ^(4) theta + sin ^(2) 2 theta) + 4 cot theta cos ^(2) ((pi)/(4) -(theta)/(2)) is .............. A) -2 cot theta B) 2 cot theta C) 2 cos theta D) 2 sin theta

If sec theta=sqrt(2) and (3 pi)/(2)

If pi/2 < theta < (3pi)/2 then write the value of sqrt((1+cos2theta)/2)
