For non -zero vectors `a` and `b` if `|bara + barb| < |bara - barb|` |then `bara` and `barb` are

If bara,barb,barc " are three non zero vectors, and " bara.barb = bara.barc rArr

If barr.bara=barr.barb=barr.barc=0 for non-zero vector barr then the value of (bara barb barc) is

If barr.bara=barr.barb=barr.barc=0 for non-zero vector barr then the value of (bara barb barc) is

If barx.bara=barx.barb=barx.barc=0 for some non-zero vector barx and abs(bara)=abs(barb)=abs(barc)=1 then the volume of parallelopiped with bara,barb,barc is

For non-zero vectors bara,barb,barc prove that abs(baraxxbarb.barc)=absbaraabsbarbabsbarc holds if and only if bara.barb=barb.barc=barc.bara=-

If bara and barb are non-zero vectors such that abs(bara+barb)^(2) = absbara^(2) +absbarb^(2) , then find the angle between bara and barb

IF the non-zero vectors bara and barb are perpendiculars to each other than the solution of the equation barr times bara=barb is given by

Let bara,barb and barc be non-zero vectors such that (bara times barb)times barc=1/3|barb||barc|bara . If theta is the obtuse angle between the vectors barb and barc then sin theta equals
