if `hata, hatb and hatc` are unit vectors. Then `|hata - hatb|^(2) + |hatb - hatc|^(2) + | vecc -veca|^(2)|` does not exceed

if hata, hatb and hatc are unit vectors. Then |hata - hatb|^(2) + |hatb - hatc|^(2) + | vecc -veca|^(2) does not exceed

if hata, hatb and hatc are unit vectors. Then |hata - hatb|^(2) + |hatb - hatc|^(2) + | vecc -veca|^(2) does not exceed

hata, hatb and hatc are unit vectors. If the hata +hatb = hatc , them the magnitude of hata -hatb is :

If hata and hatb are unit vectors inclined at angle theta then (1)/(2)|hata+hatb| is

If hata,hatb and hatc are three unit vectors such that hata + hatb + hatc is also a unit vector and theta_(1),theta_(2) and theta_(3) are angles between the vectors hata,hatb,hatb,hatc and hatc,hata, respectively m then among theta _(1),theta_(2)and theta_(3)

If hata,hatb and hatc are three unit vectors such that hata + hatb + hatc is also a unit vector and theta_(1),theta_(2) and theta_(3) are angles between the vectors hata,hatb,hatb,hatc and hatc,hata, respectively m then among theta _(1),theta_(2)and theta_(3)
