Dot product of scalar

WebThe Dot Product (Inner Product) There is a natural way of adding vectors and multiplying vectors by scalars. Is there also a way to multiply two vectors and get a useful result? It turns out there are two; one type produces a scalar (the dot product) while the other produces a vector (the cross product). We will discuss the dot product here. WebThe dot product is a scalar; the cross product is a vector. Later chapters use the terms dot product and scalar product interchangeably. Similarly, the terms cross product and vector product are used interchangeably. Summary. There are two kinds of multiplication for vectors. One kind of multiplication is the scalar product, also known as the ...
