" 31.The value of "tan((pi)/(4)+theta)-tan((pi)/(4)-theta)" is "

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

tan((pi)/(4)+theta)-tan((pi)/(4)-theta)=2tan2 theta

(ii)Find the value of tan(pi/4+theta)tan(pi/4-theta)

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=3, then the value of tan^(2)((pi)/(4)+theta)+tan^(2)((pi)/(4)-theta)

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=4 then theta=

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

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

tan ((pi)/(4)+theta) tan ((3pi)/( 4) + theta) is equal to

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

tan(pi/4+theta)tan((3pi)/4+theta) is equal to
