If for three non zero vectors `veca,vecb` and ` vecc `; `veca.vecb = veca.vecc` and `vecaxxvecb = vecaxxvecc`, the show that `vecb = vecc`.

veca,vecb,vecc are non zero vectors. If vecaxxvecb=vecaxxvecc and veca.vecb=veca.vecc then show that vecb=vecc .

If veca.vecb=veca.vecc, vecaxxvecb=vecaxxvecc and veca!=vec0, then prove that vecb=vecc.

For three non - zero vectors veca, vecb and vecc , if [(veca, vecb , vecc)]=4 , then [(vecaxx(vecb+2vecc), vecbxx(vecc-3veca), vecc xx(3veca+vecb))] is equal to

If veca , vecb and vecc are non-zero vectors, then vecaxxvecb = vecaxxvecc

For non zero vectors veca,vecb, vecc |(vecaxxvecb).vecc|=|veca||vecb||vecc| holds iff

For non zero vectors veca,vecb, vecc (veca xx vecb). Vecc= |veca| |vecb||vecc| holds iff:

For non-zero vectors veca, vecb and vecc , |(veca xx vecb) .vecc = |veca||vecb||vecc| holds if and only if

For non-zero vectors veca, vecb and vecc , |(veca xx vecb) .vecc = |veca||vecb||vecc| holds if and only if

For three non - zero vectors veca, vecb and vecc , if [(veca, vecb and vecc)]=4 , then [vecaxx(vecb+2vecc)vecbxx(vecc-3veca)vecc xx(3veca+vecb)] is equal to

For non zero vectors veca,vecb, vecc |(vecaxxvecb).vec|=|veca||vecb||vecc| holds iff
