If `bara,barb,barc` are non-coplanar vectors, express `bara times (barb times barc)` as a linear combination of `bara,barb,barc`

If bara,barb,barc are non -coplanar unit vectors such that bara times (barb times barc)=((barb+barc))/sqrt2, barb and barc are non parallel then prove that angle between bara and barb is 3pi//4

IF bara,barb,barc and bard are any four vectors then (bara times barb) times (barc times bard) is a vector

If bara, barb,barc are non-coplanar vectors, then (bara+barb+barc).(bara+barb)xx(bara+barc)=

If bara,barb,barc be any three non-coplanar vectors, then [bara+barb" "barb+barc" "barc+bara]=

If bara,barb,barc are three coplanar vectors, then [bara+barb" "barb+barc" "barc+bara]=

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

If bara,barb and barc are three non-coplanar vectors, then : (bara + barb + barc) · [(bara + barb) xx (bara + barc)] =

lf bara,barb,barc are coplanar unit vectors, then [2bara-barb,2barb-barc,2barc-bara]=

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 =
