a) Find a vector, w of magnitude 3 that is in the opposite direction to the vector. u = (2 1, 4). = b) Let u=(-4, 3, 0) and v = (2, -1, -2) be vectors. Find the angle between u and v. Give the answer in two (2) decimal places. c) Find the area of the parallelogram with vertex at the origin where the vectors a=2i-j+k and b = i +3j-k as edges. a) Find a vector, w of magnitude 3 that is in the opposite direction to the vector. u = (2 1, 4). = b) Let u=(-4, 3, 0) and v = (2, -1, -2) be vectors.
