Actually, I understand the perpendicularness, but wouldn't using that equation find the smallest distance between the velocity vector and position of the plane at any time? Not the plane and station?
This may be a bit too much.
If $\displaystyle \ell_1=P+tD~\&~\ell_2=Q+tE$ are skew lines (neither are parallel nor do they intersect) then the distance between them is:
$\displaystyle \frac{{\left| {\overrightarrow {PQ} \cdot \left( {D \times E} \right)} \right|}}{{\left\| {D \times E} \right\|}}$
I've covered the basics of vectors but we'll go into more detail when we do vector calculus.
I have a new question if anyone could help me?
Let g: R \ {-13/4 } --> R be another function with f[g(x)] = 3 / (4x + 13). Find the rule of g(x). How should I do this!?!
