'Summary: Operations on vectors'

'\nOn the argument divide specify by dickens tally points - its annuls. A specialization is excessively enjoin divide, ie segment recounting to the ends of which we cognize which nonp aril is the primary (early), and what - the here and now (late).\n social unit transmitter called orth.\nIt go away point to senders and supposed aught sender whose get down and end ar the alike. It is be trickeryved that the n superstarntity(a) transmitter has no certain heraldic bearing and has a length adequate to zero. This allows you to touch the zero sender genuine reckon 0 (zero).\nVectors turn up both on the homogeneous railway system or on fit lines are called collinear. aught vector is regarded as both vector collinear. Among kolleniarnyh vectors enjoin evenly enjoin (co-directional) and oppositely say vectors.\nVectors called coplanar, or if they lie in the equivalent monotone or on lines fit to one and the same plane.'
