Let `-pi/6beta_1` and `alpha_2>beta_2` then `alpha_1+beta_2` equals

Let -pi/6 beta_1 and alpha_2>beta_2 then alpha_1+beta_2 equals

Let -(1)/(6) beta_(1) and alpha_(2)>beta_(2), then alpha_(1)+beta_(2) equals

If sin (alpha + beta)=1, sin (alpha- beta)= (1)/(2) , then tan (alpha + 2beta) tan (2alpha + beta) =

If alpha and beta be between 0 and (pi)/(2)and if cos(alpha+beta)=(12)/(13) and sin(alpha-beta)=3/5, then sin 2 alpha is equal to

What is (1+tan alpha tan beta)^2+(tan alpha-tan beta)^2-sec^2 alpha" "sec^2beta equal to?

If sin(alpha+beta)=1,sin(alpha-beta)=(1)/(2) where alpha,beta in[0,(pi)/(2)], then tan(alpha+2 beta)tan(2 alpha+beta) is equal to
