If `alpha and beta` are positive. acute angles and `cos 2alpha=(ncos 2 beta-1)/(n-cos2 beta) (n lt 1)`, show that, `sqrt(n-1)tanalpha = sqrt(n+1) tanbeta`.

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

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=

If alpha and beta be acute angles and cos2 alpha=(3cos2 beta-1)/(3-cos2 beta), then tan alpha is :

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

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