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

If tan theta+tan(60^(@)+theta)+tan(120^(@)+theta)=3, Prove that: (3tantheta-tan^(3)theta)/(1-3tan^(2)theta)=1

If "tan" 2 theta "tan" theta =1, "then" theta =

If tan 3 theta + tan theta =2 tan 2 theta , then theta is equal to (n in Z)

tan theta + 2 tan 2 theta + 4 tan 4 theta + 8 cot 8 theta = cot theta.

Evaluate : (cos^2(45 + theta) + cos^2(45 - theta))/(tan(60^@ + theta) tan(30^@ - theta)) + cosec(75^@ + theta) - sec(15^@ - theta)

Solve tan theta + tan 2 theta + tan theta * tan 2 theta * tan 3 theta=1

Prove that: tan 8theta - tan 6theta - tan 2theta = tan 8theta \ tan 6theta \ tan 2theta .

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
