If `|veca|=2,|vecb|=sqrt3` and `(bara,barb)=30^@` then the angle between the vectors `barb` and `bara-barb` is

The vectors bara,barb and bara+barb are

The vectors bara,barb and bara+barb are

If ' theta ' is the angle between the unit vectors bara, barb," then " abs(bara+barb) =

If bara, barb, barc are unit vectors satisfying bara-sqrt(3)barb+barc=bar0 , then the angle between the vectors bara and barc is :

If bara.barb=-|vec(a)||vecb| , then the angle between bara and barb is

If bara and barb are any two non-zero vectors, then find the angle between the vectors absbarb bara+absbara barb = absbarb bara-absbara barb

Let bara and barb be vectors,satisfying |bara|=|barb|=5 and (bara,barb)=45^(@) . Find the area of the triangle having bara-2barb and 3bara+2barb as two of its sides.

IF |bara|=4,|barb|=2 and the angle between bara and barb is pi/6 then (bara times barb)^2=
