If `n tan alpha=(n+1) tan beta` then show that, `tan(alpha-beta)=(sin2beta)/(2n+1-cos2beta)`

If tan(alpha-beta)=(sin 2beta)/(3-cos2beta) , then

If" " n tan alpha = (n+1) tan beta " then show that", tan (alpha - beta) = (sin 2 beta)/(2n + 1 - cos2 beta).

If 2tanalpha=3tanbeta , then prove that then show that tan(alpha-beta)=(sin2beta)/(5-cos2beta)

If 2tanalpha=3 tanbeta , show that tan(alpha-beta)=(sin2beta)/(5-cos2beta)

If" " 2 tan alpha = 3 tan beta, " show that",tan ( alpha - beta) = (sin 2 beta)/(5- cos 2 beta).

If tan beta=3tan alpha, prove that tan(alpha+beta)=(2sin2 beta)/(1+cos2 beta)

If 2tan alpha=3tan beta, prove that tan(alpha-beta)=(sin2 beta)/(5-cos2 beta)

If 2tan alpha=3tan beta, prove that tan(alpha-beta)=(sin2 beta)/(5-cos2 beta)

If 3tan alpha=4tan beta ,then prove that tan(alpha-beta)=(sin beta*cos beta)/(3+sin^(2)beta)=(tan beta)/(4tan^(2)beta+3)

If tan beta = 3 tan alpha, prove that tan (alpha + beta) = (2sin 2beta)/(1+cos 2beta)
