[" If "tan(alpha+beta)=2" and "tan(alpha-beta)=1," then "tan(2 alpha)" is "],[" equal to "]

If tan(alpha+beta)=2andtan (alpha-beta)=1 , then tan(2alpha) is equal to

If 2tan alpha=3tan beta then tan(alpha-beta)=

If tan (alpha+beta)=a+b and tan(alpha-beta)=a-b,thenshowtâtan alpha-b tan beta=a^(2)

If sin (alpha+beta)=1, sin (alpha-beta)=1/2 , then tan (alpha+ 2beta). tan (2 alpha+beta) is equal to :

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

If tan(2alpha+beta)=x & tan(alpha+2beta)=y , then [ tan3(alpha+beta)]. [ tan(alpha-beta)] is equal to (wherever defined)

If tan(2alpha+beta)=x & tan(alpha+2beta)=y , then [ tan3(alpha+beta)]. [ tan(alpha-beta)] is equal to (wherever defined)

If tan(2alpha+beta)=x & tan(alpha+2beta)=y , then [ tan3(alpha+beta)]. [ tan(alpha-beta)] is equal to (wherever defined)

If cos( alpha+beta) + sin(alpha-beta) = 0 and 2010tan beta - 1 = 0 then tan alpha is equal to
