Differences btw X-Y Plane and R-Z Plane

  1. Dec 18, 2008 #1
    Hi guys,

    While working with coordinates, I notice that for those that deal with axi-symmetry, the R-Z plane is used.

    May I know whats the difference between the XY plane and the RZ plane?

    I mean is 1 unit along the X-axis the same as 1 unit along the R axis or is there a conversion?

    Thanks and Best Rgds

    Hi Skyeagle! :smile:
    I assume you're talking about cylindrical coordinates, r z and theta (or phi)?

    Yes, the unit r vector is the same length as the unit x y or z vector. :smile:
