if cos alpha + cos beta + cos gamma = sin alpha + sin beta + sin gamma = 0 , prove that cos 2 alpha + cos 2 beta + cos 2 gamma = sin 2 alpha +sin 2 beta +sin 2 gamma

if cos alpha + cos beta + cos gamma = sin alpha + sin beta + sin gamma = 0 , prove that cos 2 alpha + cos 2 beta + cos 2 gamma = sin 2 alpha +sin 2 beta +sin 2 gamma
