Linear algebra. Question in the comments

Answer 1

Can someone explain how I can approach this question?

Answer 2

I've successfully completed this question before but I can't seem to do it again.

Answer 3

Just to check, did you get \(\frac12(\mathbf u−\mathbf v)\)?

Answer 4

No, the answer was W=[-3/2,4,3](transposed)

Answer 5

The trick is to plot the vectors and follow the instructions.

Answer 6

Well, since they're in \(\mathbb R^3\), that might be a little tough.

Answer 7

I would find the vector eq for the tip, the vector eq for the head and subtract the head and tip

Answer 8

I meant to say tail, not tip.

Answer 9

Would the tail be located at -u/2?

Answer 10

I see what I have done.
