I was wondering if this is correct:
"The dot product of two vectors, where vector u gets multiplied by a real number t."
(t$\vec{u})\cdot\vec{v}$ = u$\cdot (t \vec{v})$, t$\in\Bbb{R}$
At first, I thought the professor just missed the arrow above u on the right side of the equation, but it said the same thing when I checked the notes. It does not feel right, but I know too little about vectors to say for sure. If this is right, how do I use u as a non-vector?
