" 17."tan theta+tan[(pi)/(3)+theta]+tan[(2 pi)/(3)+theta]=3

tantheta + tan(pi/3 + theta) +tan((2pi)/3 + theta)=3

If tan theta + tan((pi)/(3)+theta) + tan((-pi)/(3)+theta) = ktan 3 theta then the value of k is

tan theta tan((pi)/(3)+theta)tan((pi)/(3)-theta)=tan3 theta

tantheta+tan(pi/3+theta)+tan((2pi)/(3)+theta)=3

tantheta+tan(pi/3+theta)+tan((2pi)/(3)+theta)=3

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 ]=a " then " tan^(3)[(pi)/(4)+ theta ] + tan^(3)[(pi)/(4)- theta]=

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

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