If `f(theta)=(1-sin2theta+cos2theta)/(2cos2theta)` , then value of `8f(11^0)f(34^0)` is ____

If f(theta)=(1-sin2 theta+cos2 theta)/(2cos2 theta), then value of 8f(11^(0))*f(34^(0))^(0) is

If f(theta)=(1-sin2 theta+cos2 theta)/(2sin2 theta) then value of f(11^(@))*f(34^(@)) is

(1+sin2theta+cos2theta)/(1+sin2theta-cos2theta) =

Range of f(theta)=cos^2theta(cos^2theta+1)+2 sin^2theta is

cos^(2)theta-sin theta.cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

If f(theta)=(sin theta+csc theta)^(2)+(cos theta+sec theta)^(2) then minimum value of f(theta) is 7894. None of these
