If `0lt=alpha,betalt=90^@` and `tan(alpha+beta)=3` and `tan(alpha-beta)=2` then value of `sin2alpha` is

If 0 le alpha, beta le 90^(@) and tan(alpha+beta)=3 and tan(alpha-beta)=2, then value of cos 2 beta is :

tan (alpha + beta) =1/2, tan(alpha - beta) = 1/3 "then the value of" tan^(2) alpha is-

If alpha+beta=90^(@) and beta+gamma=alpha then tan alpha-tan beta=?

tan(alpha+beta)=(1)/(2),tan(alpha-beta)=(1)/(3), then find the value of tan2 alpha

If 0lt betalt alpha lt(pi/4),cos(alpha+beta)=3/5 and cos(alpha-beta)=4/5 then find the avlue of sin 2 alpha

If sin beta=sin(2alpha+beta) , then tan(alpha+beta)-2tan alpha is

If sin alpha=A sin(alpha+beta),Ane0 , then The value of tan alpha is

If sin alpha=A sin(alpha+beta),Ane0 , then The value of tan alpha is

If sin alpha=A sin(alpha+beta),Ane0 , then The value of tan alpha is
