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

If alpha and beta are acute angles and cos2 alpha=(3cos2 beta-1)/(3-cos2 beta). Prove that :tan alpha=sqrt(2)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 cos 2alpha = (3cos2beta -1)/(3-cos2 beta) prove that tan alpha tan beta= sqrt2 :1 .

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

alpha and beta are acute angles and cos2alpha = (3cos2beta-1)/(3-cos2beta) then tan alpha cot beta =

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

alpha and beta are acute angles and cos2 alpha=(3cos2 beta-1)/(3-cos2 beta) then tan alpha cot beta=
