If ` veca=hati-hatk,vecb=xhati+hatj+(1-x)hatk,vecc=yhati+xhatj+(1+x-y)hatk ` show that ` [veca,vecb,vecc] ` depends on neither .x nor y.

Let veca =hati -hatk, vecb = xhati+ hatj + (1-x)hatk and vecc =y hati +xhatj + (1+x -y)hatk . Then veca, vecb and vecc are non-coplanar for

veca=2hati+3hatj-hatk vecb=hati-hatj-m hatk vec c= -hati+2hatj+hatk and [veca, vecb, vec c]=8 then m is :

If veca=2hati+3hatj+hatk, vecb=hati-2hatj+hatk and vecc=-3hati+hatj+2hatk , then [veca vecb vecc]=

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find veca*(vecb xx vec c) .

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find (veca xx vecb)xxvec c

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find veca xx (vecb xx vec c)

If veca=hati+hatj+hatk,vecb=2hati+xhatj+hatk,vecc=hati-hatj+4hatk and veca.(vecbxxvecc)=70 , then x is equal to

if veca=hati+hatj+hatk,vecb=2hati+xhatj+hatk,vecc=hati-hatj+4hatk and veca*(vecbxxvecc)=70 , then x=

If veca=xhati + y hatj + zhatk, vecb= yhati + zhatj + xhatk and vecc= zhati + xhatj+ yhatk ,, " then " vecaxx (vecbxx vecc) is
