Beta Gamma Gamma

beta gamma gamma omega psi phi alpha beta + beta gamma + gamma alpha alpha beta + beta gamma + gamma alpha formula alpha beta + beta gamma + gamma alpha is equal to sin(beta-gamma)cos(alpha-delta)+sin(gamma-alpha)cos(beta-delta)+sin(alpha-beta)cos(gamma-delta)=0 cos alpha+cos beta+cos gamma+cos(alpha+beta+gamma) if alpha beta gamma are such that alpha+beta+gamma=2 1/(alpha*beta) + 1/(beta*gamma) + 1/(gamma*alpha) = tan(alpha+beta-gamma)/tan(alpha-beta+gamma) prove that beta m n gamma(m)gamma(n) if alpha+beta-gamma=pi then sin^(2alpha+sin^(2beta-sin^(gamma= cos(alpha+beta)cos gamma-cos(beta+gamma)cos alpha=sin beta sin(gamma-alpha)
