[" (ii) If "sin2 alpha=4sin2 beta," show that,"],[qquad 5tan(alpha-beta)=3tan]

If sin2 alpha=4sin2 beta, show that 5tan(alpha+beta)=3tan(alpha+beta)

If sin 2 alpha = 4 sin 2 beta, "show that", 5tan ( alpha -beta) = 3 tan ( alpha +beta)

if tan alpha=2tan beta show that (sin(alpha+beta))/(sin(alpha-beta))=3

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

If sin beta = 1/5 sin(2alpha +beta) , show that tan(alpha +beta) = 3/2 tan alpha .

If cos alpha+cos beta=1/3 and sin alpha+sin beta=1/4 ,show that tan((alpha+beta)/2)=3/4

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

If 3 sin alpha=5sin beta then (tan((alpha+beta)/2))/(tan((alpha-beta)/2))=

if tan alpha = 2tanbeta show that (sin(alpha+beta))/(sin(alpha-beta)) = 3

If 5sin alpha=3sin(alpha+2 beta)!=0, then tan(alpha+beta) is equal to
