A scalar product between two vectors is a scalar quantity that represents the "dot product" of the two vectors. It is denoted by the symbol . The scalar product of two vectors is calculated by multiplying the corresponding elements of the two vectors and then summing the results.
where:
and are the two vectors.
and are the elements of the vectors in their respective positions.
A vector product between two vectors is a vector quantity that represents the "cross product" of the two vectors. It is denoted by the symbol (\times). The vector product of two vectors is calculated by multiplying the corresponding elements of the two vectors and then summing the results.
where:
and are the two vectors.
and are the elements of the vectors in their respective positions.
The scalar and vector products are both linear operations, which means that they satisfy the following properties:
$(a + b) \cdot c = a \cdot c + b \cdot c
$(a - b) \cdot c = a \cdot c - b \cdot c
$(a \cdot b) \cdot c = a \cdot (b \cdot c)
These properties ensure that the scalar and vector products are well-defined for any vectors (\mathbf{a}) and (\mathbf{b})
