If \(\alpha\) + \(\beta\) + \(\gamma\) = 2\(\pi\), then the system of equations
x + (cos \(\gamma\))y + (cos \(\beta\))z = 0
(cos \(\gamma\))x + y + (cos \(\alpha\))z = 0
(cos \(\beta\))x + (cos \(\alpha\))y + z = 0
has :
x + (cos \(\gamma\))y + (cos \(\beta\))z = 0
(cos \(\gamma\))x + y + (cos \(\alpha\))z = 0
(cos \(\beta\))x + (cos \(\alpha\))y + z = 0
has :
