This water is two down Now off this called Cube You know, we assume the last of if its edges is equal to one. So two buck chair of the diagonal of this cube is he coached you We use these for two one one on one and a Taliban off one is faces This factor this is you call Chiu one Cyril on one. Everything out angle between this two actors, He's dead. So we have consign later is equal to you. Got three over magnitudes A few taps magnitude Tau V This is a culture true over you.
