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

Prove that tan8theta - tan6theta - tan2theta= tan8theta tan6theta tan2theta

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

Prove that 1 + tan 2 theta tan theta = sec 2 theta .

General solution of the equation tan theta + tan 4 theta + tan 7 theta = tan theta cdot tan 4 theta cdot tan 7 theta "is" theta =

Solve: tan4 theta = tan2theta

Prove that cot 2 theta + tan theta = cosec 2 theta

Prove that : tan 4 theta = (4 tan theta - 4 tan^3 theta)/(1-6 tan^2 theta + tan^4 theta) .

Prove that (tan^2 (2theta)-tan^2 theta)/(1-tan^2 (2theta) tan^2 theta)=tan (3theta)tan theta

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

Prove that cot theta-tan theta=2cot 2 theta .
