Homework Help: Corrdinate system

  1. Feb 10, 2008 #1
    1. The problem statement, all variables and given/known data
    A bug is on one wall of a room. The lower left-hand corner of the wall is selected as the origin of a two-dimensional Cartesian coordinate system. The bug is located at the point having coordinates (1.8, .8) m

    How far is it from the corner of the room?
    What is it's location in polar coordinates?

    r=?????
    theta=????
    2. Relevant equations



    3. The attempt at a solution

    Aren't these two question asking for the same thing? I need to use the pythagorean theorem right?

    Thank you very much

    The radius in the polar system is the distance - it also has a direction

    Thank you very much

    That makes sense, but aren't these two questions asking for the same thing?

    Thank you

    No, polar coordinates have both an angle and radius from origin.
