यदि सदिश `bara, barb, barc` एक‌ त्रिभुज की क्रम से ली गई भुजाएं निरूपित करें तो सदिश `bara+barb+barc` का मान लिखिए।

[bara barb barc]+[bara barc barb] =

[[bara-barb, barb-bara, barc-bara]]=

If vectors bara,barb,barc are non-coplaner, then ( [ bara+2barb barb+2barc barc+2bara ] )//( [ bara barb barc ] ) =

If bara,barb,barc are unit coplanar vectors, then find [ 2bara-barb 2barb-barc 2barc -bara] .

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

If bara. barb = barb. barc = barc . bara = 0 then [bara barb barc] =

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

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