math problem: transform polar co-ordinates wrt new origin


    Nov 08 2012 | 9:43 am
    Hi all,
    This is more maths than Max, but I thought here would be a good place to ask.
    If a point has co-ordinates (r, theta) with respect to one point in space, how do I work out its co-ordinates with respect to another, known, location?
    It's a spacialisation thing.
    TIA

      That will do nicely, thank you.
      (just couldn't get my brain around it)
      best

      Funny i thought about this problem a while yesterday and came to somewhat the same thought that it should be fairly easy when you are in the cartesian system. But i felt stupid telling you this, because i thought there must be some way to do it without the conversion. Is there a way to do that?
