Dot product - Wikipedia
In mathematics, the dot product or scalar product[note 1] is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. …
Dot Product - Math is Fun
When two vectors are at right angles to each other the dot product is zero. a · b = | a | × | b | × cos (θ) or we can calculate it this way: a · b = a x × b x + a y × b y. This can be a handy way to find …
