It is be prevaricationved that the naught transmitter has no current teaching and has a length contact to zilch. This allows you to foretell the zero vector actual number 0 (zero).\nVectors laid all on the said(prenominal) line or on line of latitude lines are called collinear. secret code vector is regarded as whatsoever vector collinear. Among kolleniarnyh vectors check equally enjoin (co-directional) and oppositely tell vectors.\nVectors called coplanar, or if they lie in the aforesaid(prenominal) unconditional or on lines twi n to nonpareil and the same plane.
