`If" "alpha " and " beta` are positive acute angles and `cos 2 alpha = (3 cos 2 beta-1)/(3-cos 2 beta),"show that", tan alpha = sqrt2 tan beta`

If alpha and beta are positive.acute angles and cos2 alpha=(n cos2 beta-1)/(n-cos2 beta)(n<1), show that sqrt(n-1)tan alpha=sqrt(n+1)tan beta

cos 2 alpha =(3 cos 2 beta -1)/( 3-cos 2 beta), then tan alpha=

cos 2 alpha =(3 cos 2 beta -1)/( 3-cos 2 beta), then tan alpha=

If alpha and beta are positive acute angles and cos2alpha=(3cos2beta-1)/(3-cos2beta) ,then prove that tan alpha=sqrt2tanbeta

If " "alpha " and " beta " are positive acute angles and " cos 2 alpha = (n cos 2 beta-1)/(n- cos 2 beta) (n>1), show that sqrt (n-1)tan alpha = sqrt(n+1) tan beta.

If alpha, beta are acute angles and cos 2 alpha=(3 cos 2 beta-1)/(3-cos 2 beta) then

If alpha,beta are acute angles and cos2alpha=(3cos2beta-1)/(3-cos2beta) , then prove that tan alpha=sqrt2 tan beta

If alpha and beta be two acute angles and cos2alpha=(3cos2beta-1)/(3-cos2beta) ,show that tan alpha=sqrt2tanbeta

If alpha and beta are acute angles and cos2 alpha=(3cos2 beta-1)/(3-cos2 beta). Prove that :tan alpha=sqrt(2)tan beta
