[tan beta=2sin alpha sin gamma cosec(c],[in],[A*p*b)cos pquad c)H*p]

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

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

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 alpha,beta,gamma "are in A.P. show that" cot beta = (sin alpha - sin gamma)/(cos gamma -cos alpha)

If alpha,beta,gamma are ccute angles and cos theta=sin beta/sin alpha,cos varphi=sin gamma sin alpha and cos(theta-varphi)=sin beta sin gamma, then the value of tan^(2)alpha-tan^(2)beta-tan^(2)gamma is equal to (a)-1(b)0 (c) 1(d)2

If alpha,beta,gamma are in A.P. show that cot beta=(sin alpha-sin gamma)/(cos gamma-cos alpha)

If tan beta=(tan alpha + tan gamma)/(1+ tan alpha . tan gamma) Prove that sin 2 beta =(sin 2 alpha + sin 2 gamma)/(1+ sin 2 alpha . Sin 2 gamma)
