If: `tan theta + tan(pi/2 - theta)=2`, then: `theta =`

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

Prove the following identities: tan theta tan(pi/3 + theta) tan(pi/3 - theta) = tan 3 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 ) =3 , " then " tan^(2)(pi//4 + theta ) + tan^(2)(pi//4 - theta ) =

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

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

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

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

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