    Remember that the magnitude \(|\vec{a}|\) and dot product \(\vec{a}\cdot\vec{b}\) both operate on *vector(s)* to yield a *scalar*.

    also just to double check, you cant multiply a vector and a scalar together right

    The last is valid? Are you sure? It's a dot product between a scalar and vector.
