tan((pi)/(4)+theta)-tan((pi)/(4)-theta)=?

"Tan((pi)/(4)-theta)tan((pi)/(4)+theta)=

tan((pi)/(4)+theta)xx tan((3 pi)/(4)+theta)=-1

Tan ((pi)/(4)+theta).Tan((3pi)/(4)+theta)=

Solve : tan ((pi)/(4)+ theta) + tan ((pi)/(4) - theta) = 4

Prove that tan ((pi)/(4) + theta) tan ((3pi)/(4) + theta) = -1

If tan ((pi)/(4) + theta) + tan ((pi )/(4) - theta) = p sec 2 theta) then the vlaue of p is equal to :

Assertion (A) : If Tan((pi)/(4)+ theta)+Tan ((pi)/(4)- theta)=k then Tan^(3)((pi)/(4)+ theta)+Tan^(3) ((pi)/(4)- theta)=k^(3)-3k Reason (R) : If A+B=(pi)/(2) then Tan A tan B=1

Prove that tan ((pi)/(4) + theta)- tan ((pi)/(4) - theta) = 2 tan 2 theta .

The solution of the equation tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=4 is given by theta =
