Vector dot products: (2,2) x (-2,0) = (-4,0) = -4; (2,2) x (-2,2) = (-4,4) = 0; (2,2) x (2,2) = (4,4) = 8
Note:True dot products are only produced when the length of both vectors is 1. The normalisation step has been skipped in the following demonstration to make its equations simpler (but the positive/zero/negative rule still applies).File history
