Title: 9_3 The Scalar Product
Course: HELM Workbooks 2023-2024 > Section: HELM 9: Vectors

There are two kinds of multiplication involving vectors.

The first is known as the scalar product or dot product. This is so-called because when the scalar product of two vectors is calculated the result is a scalar. We can take the scalar product of any two vectors of the same size.

The second product is known as the vector product. When this is calculated the result is a vector. The vector product is only defined for vectors in \(\mathbb{R}^3\).

The definitions of these products may seem rather strange at first, but they are widely used in applications. We will only consider the scalar product in this quiz.
