Each of the following expressions has a single numerical value for all θ where the expression is defined. Determine the numerical value of each expression and make sure to enter a single number. √36⋅cos^2(θ)+36⋅sin^2(θ)=

7/sec^2(θ)−tan^2(θ)=

(cos^2(θ)+sin^2(θ))(sec^2(θ)−tan^ 2(θ))=

sin(θ)/csc(θ)+cos(θ)/sec(θ)=
