(1+cos alpha)(1+cos beta)(1+cos gamma)=(1-cos alpha)(1-cos beta)(1-cos gamma)
(1+cos alpha)(1+cos beta)(1+cos gamma) /(1-cos alpha)(1-cos beta)(1-cos gamma) =1

2cos square alpha ×2cos square beta × 2cos square gamma / 2sin square alpha ×2sin square beta × 2sin square gamma = 1
cos square alpha ×cos square beta × cos square gamma = sin square alpha × sin square beta × sin square gamma
cos alpha×cos beta×cos gamma = sin square alpha×sin square beta×sin square gamma
