If `veca,vecb,vec c` are unit vectors such that `veca+vecb+vec c= vec0` find the value of `veca.vecb+vecb.vec c+ vec c. veca`

if veca , vecb ,vecc are three vectors such that veca +vecb + vecc = vec0 then

If vec a,vec b , vec c are unit vectors such that veca + vec b+ vecc = 0 and lambda = veca.vecb + vecb.vecc+vecc.veca and d = veca xx vecb + vecb xx vecc + vecc xx veca , then (lambda,vecd) is

If |veca|=3, |vecb|=1, |vecc|=4 and veca + vecb + vecc= vec0 , find the value of veca.vecb+ vecb+ vecc.vecc + vecc.veca .

If veca,vecb,vecc be three vectors such that [veca vecb vec c]=4 then [vecaxxvecb vecbxxvecc veccxxveca] is equal to
