If `3lambda vecc +2mu(veca xx vecb )=0,` then

Unit vector vecc is inclined at an angle theta to unit vectors veca and vecb which are perpendicular. If vecc=lambda(veca+vecb)+mu(veca xx vecb), lambda, mu real, then theta belongs to:

Unit vector vecc is inclined at an angle theta to unit vectors veca and vecb which are perpendicular. If vecc=lambda(veca+vecb)+mu(veca xx vecb), lambda, mu real, then theta belongs to:

Prove that veca xx (vecb xx vecc) + vecb xx (vecc xx veca) + vecc xx (veca xx vecb) = vec0 and hence prove that veca xx (vecb xx vecc), vecb xx (vecc xx veca), vecc xx (veca xx vecb) are coplanar.

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

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

Let veca vecb and vecc be three non-zero vectors such that veca + vecb + vecc = vec0 and lambda vecb xx veca xx veca + vecbxxvecc + vecc + veca = vec0 then find the value of lambda .

If veca, vecb, vecc are unit vectors such that veca. vecb=0, (veca-vecc).(vecb+vecc)=0 and vecc=lambdaveca+muvecb+omega(veca xx vecb) , where lambda, mu, omega are scalars, then

If veca, vecb, vecc are unit vectors such that veca. vecb=0, (veca-vecc).(vecb+vecc)=0 and vecc=lambdaveca+muvecb+omega(veca xx vecb) , where lambda, mu, omega are scalars, then

If veca, vecb, vecc are unit vectors such that veca. vecb=0, (veca-vecc).(vecb+vecc)=0 and vecc=lambdaveca+muvecb+omega(veca xx vecb) , where lambda, mu, omega are scalars, then

If veca, vecb, vecc are unit vectors such that veca. vecb=0, (veca-vecc).(vecb+vecc)=0 and vecc=lambdaveca+muvecb+omega(veca xx vecb) , where lambda, mu, omega are scalars, then
