Prove that: `t a nthetatan(60^0-theta)tan(60^0+theta)=tan3thetadot`

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

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

tantheta+tan(6 0^0+theta)+tan(12 0^0+theta)=3tan3theta

tantheta+tan(6 0^0+theta)+tan(12 0^0+theta)=3tan3theta

tantheta+tan(6 0^0+theta)+tan(12 0^0+theta)=3tan3theta

Prove that tantheta*tan (60-theta)* tan (60 +theta) = tan 3theta and hence find the value of tan5^0*tan55^0*tan65^0*tan75^0

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

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

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