Lesson 13: Performing Dot Product on Vectors


Lesson on performing the dot product on vectors. If u = (a,b) and v = (c,d), dot product is done through u.v = ac+ bd. Just like any operation, dot product has properties. Keep in mind that these properties are used to better evaluate and simplify dot products.

0:30 Find the dot product of (4,5) and (2,3).
1:50 Find (u.v)w
2:50 Find u.2v
