I'm trying to solve these questions:
Given $v = [3, -6, 2]$ and $w = [-1, 6, 5]$, find;
- $v \downarrow w$
- $w \downarrow v$
- What does the magnitude of $w \downarrow v$ depend on?
- What does the direction of $w \downarrow v$ depend on?
I already figured out the answer to 1 and 2, since they are pretty straightforward. But I don't really know the answer to 3 and 4.
