Question

The minimum value of expression sin alpha + sin beta + sin gamma where alpha, beta, gamma are positive real number satisfying alpha + beta + gamma = pie is

Answer 1

Answer:

α, β, γ are real numbers satisfying α + β + γ = π. The minimum value of the given expression sin α + sin β + sin γ is. From this, we can say that the minimum value of sin α + sin β + sin γ is greater 0, i.e. positive.
