I kinda remember some identity which goes as follows:(adsbygoogle = window.adsbygoogle || []).push({});

If [tex]a,b,c[/tex] are coplanar, non collinear vectors then

[tex]\alpha a + \beta b + \gamma c = 0[/tex]

=> [tex]\alpha + \beta + \gamma = 0[/tex]

or something like this. Can someone help me remember.
