IF cos (alpha +beta )=(5)/(13) and cos (alpha - beta )=(4)/(5), then find the value of tan 2 beta .

If sin ( alpha + beta ) =(4)/(5) and sin (alpha - beta ) =(5)/(13), find the value of tan 2 alpha

If sin(alpha+beta)=(4)/(5), sin(alpha-beta)=(5)/(13) , find the value of tan 2alpha :

In sin alpha+ sin beta=(1)/(2) and cos alpha+ cos beta =(5)/(4) , find the value of tan alpha+tan beta .

If cos(alpha+beta)=(4)/(5);sin(alpha-beta)=(5)/(13) and alpha,beta lie between 0&(pi)/(4) then find the value of tan2 alpha

cos(alpha-beta)=(3)/(5),sin(alpha+beta)=(5)/(13) then tan2 alpha

If sin(alpha + beta) = 4/5 and sin (alpha - beta)= 5/13 , find the value of tan 2 alpha .

If alpha, beta in (0, (pi)/(2)), sin alpha = (4)/(5) " and " cos (alpha + beta) = - (12)/(13), then the value of sin beta is

If cos(alpha+beta)=(4)/(5) and sin(alpha-beta)=(5)/(13) , where alpha lie between 0 and (pi)/(4) , then find that value of tan2alpha .
