Unformatted text preview: 2.4 Vector Dot Product Dot Product : a specific multiplication operation that yields a scalar (a number, no associated direction). It is useful for finding the angle between two vectors, and the projection of one vector onto another vector (i.e., the component of one vector in the direction of another vector). Multiplication of a Vector by another vector : there are infinitely many ways that we could define what it means to multiply two vectors together. Only a very small number of such multiplication operations yield something physically meaningful. The dot product between two vectors A and B is defined to be : A B = A B cos where is the angle between the two vectors ( 0 180 ) . The dot product between two vectors results in a scalar ....
