Vectors u = 6(cos 601 + sin60), v = 4(cos 3151 + sin315), and w = -12(cos 3301 + sin330) are given. Use exact values when evaluating sine and cosine. Part A: Convert the vectors to component form and find -7(u v). Show every step of your work. (4 points) Part B: Convert the vectors to component form and use the dot product to determine if u and w are parallel, orthogonal, or neither. Justify your answer. (6 points)
