WebA dot product is a way of multiplying two vectors to get a number, or scalar. Algebraically, suppose A = ha 1;a 2;a 3iand B = hb 1;b 2;b 3i. We nd the dot product A B by multiplying the rst component of A by the rst component of B, the second component of A by the second component of B, and so on, and then adding together all these products.
