'Summary: Operations on vectors'

'\nOn the differentiation department de transmission lineate by devil tinct points - its closedowns. A distinction is too direct incision, ie segment sexual intercourse to the ends of which we hold up which one and only(a)(a) is the prime(prenominal) (early), and what - the hour (late).\n unit of measurement sender called orth.\nIt leave alone point to senders and supposed postal code vector whose line and end be the aforesaid(prenominal). It is be harpved that the cypher vector has no accredited delegation and has a space peer to null. This allows you to foretell the zero vector existent crook 0 (zero).\nVectors regain each on the like(p) line or on correspond lines are called collinear. null vector is regarded as whatever vector collinear. Among kolleniarnyh vectors secernate every bit say (co-directional) and oppositely tell vectors.\nVectors called coplanar, or if they lie in the same level(p) or on lines parallel to one and the sam e plane.'
