यदि `veca,vecb,vecc` बराबर परिमाण के परस्पर लम्ब सदिश हो तो दिखाइए कि सदिश `veca+vecb+vecc` सदिशों `veca,vecb,vecc` से बराबर कोण बनाता है।

[veca+2vecb-vecc,veca-vecb,veca-vecb-vecc] =

[veca+2vecb-vecc,veca-vecb,veca-vecb-vecc]=

Simplify : [veca-vecb,vecb-vecc,vecc-veca] .

[ veca + vecb vecb + vecc vecc + veca ]=[ veca vecb vecc ] , then

The vectors veca-vecb,vecb-vecc,vecc-veca are

If veca, vecb and vecc be any three non coplanar vectors. Then the system of vectors veca\',vecb\' and vecc\' which satisfies veca.veca\'=vecb.vecb\'=vecc.vecc\'=1 veca.vecb\'=veca.veca\'=vecb.veca\'=vecb.vecc\'=vecc.veca\'=vecc.vecb\'=0 is called the reciprocal system to the vectors veca,vecb, and vecc . The value of [veca\' vecb\' vecc\']^-1 is (A) 2[veca vecb vecc] (B) [veca,vecb,vecc] (C) 3[veca vecb vecc] (D) 0

If |veca| =5, |vecb| =4, |vecc| =3 and veca + vecb + vecc =0, then the vlaue of |veca, vecb + vecb.vecc+vecc,veca|, is

If veca, vecb, vecc are three non-zero vectors such that veca + vecb + vecc=0 and m = veca.vecb + vecb.vecc + vecc.veca , then:

If veca, vecb, vecc are three non-zero vectors such that veca + vecb + vecc=0 and m = veca.vecb + vecb.vecc + vecc.veca , then:
