Let the unit vectors `a` and `b` be perpendicular and the unit vector `c` be inclined at an angle `theta` to both `a` and `b`. If `c=alpha a+beta b+gamma(axxb)`, then

`x cos alpha, y = sin alpha, z= cos 2alpha`

`x =sin alpha, y = cos alpha, z = -cos 2alpha`

`x =y = cos alpha,z^(2) = cos 2alpha`

`x = y = cosalpha,z^(2) = -cos2alpha`
