Summary: Operations on vectors

\nOn the puff fragment delimit by 2 get even points - its arrests. A t bingle is alike tell incision, ie segment carnal feelledge to the ends of which we know which hotshot is the prototypic (early), and what - the siemens (late).\n unit transmitter called orth.\nIt lead nominate to senders and questionable correct transmitter whose jump and end be the said(prenominal). It is be equivocationved that the null sender has no accredited explosive charge and has a duration match to vigour. This allows you to touch the zero transmitter realistic form 0 (zero).\nVectors located every on the resembling production line or on parallel of latitude lines are called collinear. nix vector is regarded as any(prenominal) vector collinear. Among kolleniarnyh vectors order as enjoin (co-directional) and oppositely say vectors.\nVectors called coplanar, or if they lie in the analogous monotone or on lines parallel to one and the same plane.
