WebSep 17, 2024 · The dot product of a vector with itself is an important special case: (x1 x2 ⋮ xn) ⋅ (x1 x2 ⋮ xn) = x2 1 + x2 2 + ⋯ + x2 n. Therefore, for any vector x, we have: x ⋅ x ≥ 0. x ⋅ x = 0 x = 0. This leads to a good definition of length. Fact 6.1.1. The length of a vector x in Rn is the number. WebWhen two vectors are combined using the dot product, the result is a scalar. For this reason, the dot product is often called the scalar product. It may also be called the inner product.
