Web$\begingroup$ I think the cosine comes from the cosine rule and not the compound angle formula. Given 2 vectors $\vec{a}$ and $\vec{b}$ emanating from the same point. Given the angle between them and the fact that the vector opposite the angle is $\vec{b}-\vec{a}$ you can use the cosine rule and derive the formula for the dot product. $\endgroup$ – E.O.
