If alpha+beta+gamma=2 pi, then

If alpha+beta+gamma=2pi then

If alpha+beta+gamma=2pi then

If sum alpha=(2)/(3),sum alpha beta=(4)/(3) and alpha beta gamma=(8)/(3) then the equation whose roots are alpha,beta,gamma is

If alpha, beta, gamma are the roots of ax^(3) + bx^(2) + cx + d = 0 and |(alpha,beta,gamma),(beta,gamma,alpha),(gamma,alpha,beta)| = 0, alpha != beta != gamma , then find the equation whose roots are alpha + beta - gamma, beta + gamma - alpha and gamma + alpha - beta

alpha, beta, gamma are real number satisfying alpha+beta+gamma=pi . The minimum value of the given expression sin alpha+sin beta+sin gamma is
