Let `barlamda=bara times (barb +barc), barmu=barb times (barc+bara) and barv=barc times (bara+barb)`, Then

bara times (barb times barc) +barb times (barc times bara)+ barc times (bara times barb) equals

bara times (barb times barc) +barb times (barc times bara)+ barc times (bara times barb) equals

IF bara times barb = barc and barb times barc=bara then

If barc=bara times barb and barb=barc times bara then

If barc=bara times barb and barb=barc times bara then

Show that vectors bara times (barb times barc),barb times (barc times bara). barc times (bara times barb) are coplanar.

Let bara,barb and barc are three mutually perpendicular unit vectors and a unit vector barr satisfying the equation (barb - barc) times (barr times bara)+(barc - bara) times (barr times barb)+(bara-barb) times (barr -barc)=0 then barr is

If hatd is a unit vectors such that hatd=lamdabarb times barc+mubarc times bara+vbara times barb then |(hatd.bara)(barb times barc)+(bard.barb) (barc times bara)+(bard.barc) (bara times barb)| is equal to

If hatd is a unit vectors such that hatd=lamdabarb times barc+mubarc times bara+vbara times barb then |(hatd.bara)(barb times barc)+(bard.barb) (barc times bara)+(bard.barc) (bara times barc)| is equal to
