How to add two vectors
If we place the vectors at one starting point, the vectors form two sides of the parallelogram. By completing the remaining two parallel sides, we create a parallelogram. The resulting vector of the sum is the oriented diagonal of this parallelogram starting at the location point of the vectors.Analyticky - výpočtem vypočítáme součet vektorů nejjednodušeji tak, že vektory rozložíme do složek x, y, případně z. Jednotlivé vektory pak sečteme po složkách. Velikost výsledného vektoru pak dopočítáme z Pythagorovy věty z jeho složkového tvaru. Směrový vektor určíme trigonometricky - arkustangensem poměru y:x.
