If `tan beta=2sin alpha sin gamma co sec(alpha+gamma)`, then `cot alpha,cot beta,cotgamma` are in

If tan beta=2 sin alpha sin gamma "cosec" (alpha+ gamma) then cot alpha, cot beta, cot gamma are in

If tan beta = 2 sin alpha sin gamma " cosec "(alpha + gamma) , then cot alpha , cot beta and cot gamma are in

If 2 sin alphacos beta sin gamma=sinbeta sin(alpha+gamma),then tan alpha,tan beta and gamma are in

If 2 sin alphacos beta sin gamma=sinbeta sin(alpha+gamma),then tan alpha,tan beta and gamma are in

If 2 sin alpha cos beta sin gamma=sin beta sin(alpha+gamma) then tan alpha , tan beta, tan gamma are in A) A.P.B) G.P.C) H.P.D) None of these

If 2 sin alpha cos beta sin gamma =sin beta sin (alpha +gamma) then prove that tan alpha,tan beta,tan gamma are in H.P.

If 2 sin alphacos beta sin gamma=sinbeta sin(alpha+gamma),then tan alpha,tan beta and tan gamma are in

If cos(alpha + gamma)/cos(alpha - gamma) = cos 2beta then tan alpha, tan beta and tan gamma are

If : 1+sin alpha * sin beta-cos alpha* cos beta=0" ""then" : tan alpha*cot beta=
