If `veca, vecb, vecc` are mutually perpendicular vectors having magnitude 1,2,3 respectively, then `[vec(a)+vecb+vecc, vecb-veca, vecc]`=

If veca,vecb,vecc are mutually perpendicular vectors of equal magnitude show that veca+vecb+vecc is equally inclined to veca, vecb and vecc

if veca,vecb and vecc are mutally perpendicular vectors of equal magnitudes, then find the angle between vectors and veca+ vecb+vecc .

If veca, vecb, vecc are three non-coplanar mutually perpendicular unit vectors, then [(veca, vecb, vecc)] is
