Let $A_{1} A_{2} A_{3} A_{4} A_{5} A_{6} A_{1}$ be a regular hexagon. Write the $x$ -components of the vectors represented by the six sides taken in order. Use the fact that the resultant of these six vectors is zero, to prove that $\cos 0+\cos \pi / 3+\cos 2 \pi / 3+\cos 3 \pi / 3+\cos 4 \pi / 3+\cos 5 \pi / 3=0 .$ Use the known cosine values to verify the result.
Find (a) $\mathbf{u}+\mathbf{v}$, (b) $\mathbf{u}-\mathbf{v},(\mathbf{c})$ 2 $\mathbf{u}-3 \mathbf{v},$ and (d) $\mathbf{v}+\mathbf{4} \mathbf{u}$. Then sketch each resultant vector. $$\mathbf{u}=\langle-6,-8\rangle, \mathbf{v}=\langle 2,4\rangle$$
