    [SOLVED] Embarassingly simple question

    ... makes an angle 30 degrees with the positive x axis.



    ... directed at an angle 30 degrees to the positive x axis.


    What's the difference?

    I understand the "with" is using plane polar coordinate system, but i don't know what "to" means.

    I wouldn't use the second phrase myself, but I imagine the writer meant exactly the same thing. It would certainly be a very strange way of putting it if he meant anything else.

    Yep, turns out he did mean the same thing. I assumed it did, tried the question and got the correct answer. Don't much like the word either, but I guess it makes sense when using vectors.
