lf `bara· (barb xx barc) = 3`, then

bara, barb, barc are three unit vectors, barb is not parallel to barc and baraxx (barb xx barc) = 1/2barb then (bara, barb) = .... , (bara, barc) =

If bara,barb,barc are non-coplanar vectors and x, y, z are scalars such that bara = x (barb xx barc) + y (barc xx bara) + z (bara xx barb) , then x =

lf bara,barb,barc are three unit-vectors such that 3bara + 4barb + 5barc = bar0 , then

If bara xx barb=barc and barbxx barc=bara , then

If bara,barb,barc are any three vectors such that (bara+ barb) . barc = (bara - barb) . barc = 0 then (baraxx barb)xxbarc =

If bara+barb+barc =bar0 , " then " bara.bara+barb.barb+2(bara.barb)-barc.barc =

If bara, barb, barc, bard are vectors such that bard is a unit vector, the projection of bara on bard is 2 and [bara barb barc] = 3 find the value of { ( a xx b) xx (bara xx barc)} .bard

If bara ,barb and barc are three unit vectors such that bara times (barb times barc)=1/2 barb Find the angles which bara makes with barb and barc .

If bara= bari-2barj-3bark, barb=2bari+barj-bark, barc= bari+3barj-2bark then verify that bara xx (barb xx barc) = (bara.barc)barb- (bara.barb)barc .
