Question

1. Compute the angle between the vectors u = [2, -1, 1] and and v = [1, -2 , -1]

2. Given that : 1. u=[1, -3] and v=[6, 2], are u and v orthogonal?

3. if u=[1, -3] and v=[k², k] are orthogonal vectors. What is the

value(s) of k?

4. Find the distance between u=[root 3, 2, -2] and v=[0, 3, -3]

5. Normalize the vector u=[root 2, -1, -3].

6. Given that: v1 = [1, - C/7] is a unit vector, find C. and v2 = [1/2, 3/2],

find v1 + v2 and graph it.
