If `sin alpha=1/2` and `cos beta=1/2 `then `alpha+beta=`

If sin (alpha - beta) =1/2 and cos (alpha + beta) =1/2, where alpha and beta are positive acute angles, then alpha and beta are

If sin alpha-sin beta=(1)/(3) and cos beta-cos alpha=(1)/(2) show that (cot(alpha+beta))/(2)=(2)/(3)

If cos alpha+cos beta=(1)/(3) and sin alpha+sin beta=(1)/(4) prove that cos[(alpha-beta)/(2)]=+-((5)/(24))

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

sin alpha sin beta-cos alpha cos beta=1 then show that tan alpha+tan beta=0

If sin alpha=(1)/(2),cos beta=(1)/(2), find degree measure of (alpha+beta)

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 cos alpha + cos beta = 0 = sin alpha + sin beta, then value of cos 2 alpha + cos 2 beta is
