Unformatted text preview: involves multiplying two vectors together to get a scalar, not another vector (for this reason, the dot product is often referred to as a scalar product). We will use the dot product to obtain information about the length (or magnitude) of vectors, as well as to compute the degree to which two vectors "overlap." We will define the dot product in both the 2 and 3dimensional cases. The second kind of vector multiplication we will find useful is called the cross product. Contrary to the dot product, the cross product multiplies two vectors together to obtain a third vector rather than a scalar. However, we will only be able to define the cross product in the case of 3dimensional vectors. There is no cross product in the 2dimensional case....
