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 cos (alpha+beta)=(4)/(5), sin (alpha-beta)=(5)/(13) and 0 lt alpha , beta lt(pi)/(4), then tan 2 alpha=

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

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

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

If cos(alpha+beta)=(5)/(13) and cos(alpha-beta)=(4)/(5) then find the value of tan2 beta

If cos (alpha+beta)=(4)/(5), sin (alpha-beta)=(5)/(13) and 0 lt alpha, beta lt (pi)/(2) then cos 2 alpha=

If cos(alpha+beta)=(4)/(5)andsin(alpha+beta)=(5)/(13) , where alpha lie between 0and(pi)/(4) , then find that value of tan(2alpha) .
