=√[1±√(3)/2]
√[1+√(3)/2]
=√[1+1.7320508075688772935274463415059/2]
=√[1+0.86602540378443864676372317075294]
=√1.8660254037844386467637231707529
=1.3660254037844386467637231707529
√[1-√(3)/2]
=√[1-1.7320508075688772935274463415059/2]
=√[1-0.86602540378443864676372317075294]
=√0.13397459621556135323627682924706
