`tanA.tan|pi/3 + A | tan|pi/3-A | =tan 3A`

Prove the following identities: tan theta tan(pi/3 + theta) tan(pi/3 - theta) = tan 3 theta

Prove that tan 3A. tan2A.tanA = tan3A - tan 2A - tan A

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

Prove the following identities: tan 3A tan2 A tanA = tan 3 A - tan2A - tanA

tan x tan((pi)/(3)-x)tan((pi)/(3)+x)=tan3x

Prove that: (tan(pi/4+A))/(tan(pi/4-A))=((1+tanA)/(1-tanA))^(2)

Prove that: (tan(pi/4+A))/(tan(pi/4-A))=((1+tanA)/(1-tanA))^(2)

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