Dot Product: Also known as
The dot product is also known as:


 * The scalar product (but this can be confused with multiplication by a scalar so is less recommended)
 * The standard inner product.

The symbol used for the dot is variously presented; another version is $\mathbf a \bullet \mathbf b$, which can be preferred if there is ambiguity between the dot product and standard multiplication.

In the complex plane, where it is commonplace to use $\cdot$ to denote complex multiplication, the symbol $\circ$ is often used to denote the dot product.
