Question: Please help very confused Vectors u = -2(cos 30'i + sin30']), v = 6(cos 225.i + sin225*]), and w = 8(cos 120*i + sin120*j) are

Please help very confused Vectors u = -2(cos 30'i + sin30']),

Please help very confused

v = 6(cos 225.i + sin225*]), and w = 8(cos 120*i +

Vectors u = -2(cos 30'i + sin30']), v = 6(cos 225.i + sin225*]), and w = 8(cos 120*i + sin120*j) 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)
