if alpha and beta satisfy sin alpha cos beta=-(1)/(2), then the greatest value of 2cos alpha sin beta is

If alpha and beta satisfy sin alpha cos beta=-((1)/(2)), then the greatest value of 2cos alpha sin beta is

If (x) / (a) cos alpha + (y) / (b) sin alpha = 1, (x) / (a) cos beta + (y) / (b) sin beta = 1 and (cos alpha cos beta) / (a ^ (2)) + (without alpha without beta) / (b ^ (2)) = 0 then

If sinalpha=1/2 and cosbeta=1/2 , then the value of (alpha+beta) is

If sinalpha=1/2 and cosbeta=1/2 , then the value of (alpha+beta) is

alpha and beta are acute angles and cos2 alpha=(3cos2 beta-1)/(3-cos2 beta) then tan alpha cot beta=
