" Prove that "tan theta+tan(60^(@)+theta)+tan(120^(@)+theta)=3tan3 theta

Prove that tantheta+tan(60^(@)+theta)+tan(120^(@)+theta)=3tan3theta .

Prove that: tan theta tan(60^(@)-theta)tan(60^(@)+theta)=tan3 theta

Iftan theta+tan(60^(@)+theta)+tan(120^(@)+theta)=3 then theta=

If tan theta + tan(60^(@)+theta)+tan (120^(@)+theta)=3 , then theta =

If tan theta + tan (60^@+ theta) + tan (120^@ + theta)=3 then theta =

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

Prove that: tantheta.tan(60^0-theta).tan(60^0+theta)=tan3thetadot.'

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

Prove that tan theta*tan(60-theta)*tan(60+theta)=tan3 theta and hence find the value of tan5^(0)*tan55^(@)*tan65^(@)*tan75^(@)
