" 13.(a) "tan theta+tan2 theta=tan3 theta

Prove that : tan 3 theta tan 2 theta tan theta= tan3 theta-tan 2 theta-tan theta .

Solve that following equations: tan theta+tan2 theta+tan3 theta=tan theta tan2 theta tan3 theta

Prove that: "tan"3 theta tan 2theta tan theta="tan" 3theta-"tan" 2theta-"tan" theta.

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

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

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

In (0,6 pi), find the number of solutions of the equation tan theta+tan2 theta+tan3 theta=tan theta*tan2 theta*tan3 theta

If tan2 theta*tan theta=1, then theta=

Show that: If theta=(2 pi)/(7), prove that tan theta tan2 theta+tan2 theta tan4 theta+tan4 theta tan theta=
