If x Sin (90° – $\theta$) Cot (90° – $\theta$) = Cos (90° – $\theta$) then x =

If Tan $\theta$ + Cot $\theta$ = 5, then the value of $Tan^2 \theta+ Cot^2 \theta$ =

If Cosec $\theta$ – Cot $\theta$ =  $\frac 14$ then the value of Cosec $\theta$ + Cot $\theta$ is

Sin 40°=

If $\triangle XYZ$ is a right angled isosceles triangle and $\angle$ Y = 90° then XZ =

Tan $\theta$ is not defined, then $\theta$ =

Sin (90° – $\theta$) =

Tan 81° =

Sin A. Cos (90° – A) + Cos A. Sin (90° – A) =
