Q 1173056846.     Let `veca,vecb` and `vecc` be three non-coplanar vectors and let `vecp,vecq` and `vecr` be the vectors defined by

`vecp=(vecbxxvecc)/([vecavecbvecc]),vecq=(veccxxveca)/([vecavecbvecc]),vecr=(vecaxxvecb)/([vecavecbvecc])`. Then `(veca+vecb)*vecp+(vecb+vecc)*vecq+(vecc+veca)*vecr=`
