If veca=hati+hatj+hatk, vecb=hati+hatj,vecc=hati and (vecaxxvecb)xxvecc=lamda veca+mu vecb , then lamda+mu=

If veca=2hati-3hatj-hatk and vecb=hati+4hatj-2hatk , then vecaxxvecb is

Given veca=xhati+yhatj+2hatk,vecb=hati-hatj+hatk , vecc=hati+2hatj, veca botvecb,veca.vecc=4 then

If vecA=2hati-3hatj+hatk and vecB=3hati+2hatj. Find vecA.vecB and vecAxxvecB

If veca = 2 hati - 3hatj, vecb = hati + hatj -hatk, vecc = 3hati - hatk, find [a vecb vecc]

If veca=2hati+6hatj +3hatk, vecb=hati+lamdahatj+muhatk if veca xxvecb=vec0. Find value of lamda and mu.

If veca=3hati-hatj+2hatk, vecb=2hati+hatj-hatk, vecc=hati-2hatj+2hatk , find (vecaxxvecb)xxvecc and vecaxx(vecb+vecc) and hence show that (vecaxvecb)xxvecc!=vecaa(vecbxxvecc)

If veca=7hati+3hatj-6hatk , vecb=2hati+5hatj-hatk and vecc=-hati+2hatj+4hatk . Find (veca-vecb)xx(vecc-vecb) .

If veca = 3 hati -4 hatj and vecb =- 2 hati + 3 hatk, what is vecc=veca xx vecb ?

If veca=hati+hatj+hatk, veca.vecb=1 and vecaxxvecb=hatj-hatk then vecb
