#### Vector

Let $\overrightarrow a$ and $\overrightarrow b$ be two and θ the angle between them, then the scalar product between $\overrightarrow a$ and $\overrightarrow b$ is denoted by $\overrightarrow a$. $\overrightarrow b$ and is defined as the product of the magnitudes of $\overrightarrow a$ and $\overrightarrow b$ with the cosine of the angle θ.
