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

tan(pi/4+theta)-tan(pi/4-theta)=2tan2theta

If tan(pi//4+ theta ) + tan(pi//4- theta )= k sec 2 theta , then the value of k is .

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

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

tan((pi)/(4)+theta)-tan((pi)/(4)-theta)=2tan2 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)=lambda sec2 theta, them 3(b)4(c)1 ( textrmd ) 2

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=a, then tan^(2)((pi)/(4)+theta)+tan^(2)((pi)/(4)-theta)=

If tan((pi)/(4)+theta)+tan((pi)/(4)-theta)=a then tan^(3)((pi)/(4)+theta)+tan^(3)((pi)/(4)-theta)=
