Homework Help: 3D coordinate system

  1. Feb 4, 2008 #1
    1. The problem statement, all variables and given/known data

    Describe in words the region of R^3 represented by the equation or inequality.

    2. Relevant equations


    3. The attempt at a solution

    I'm not really sure how to look at the equation. I would think its just the point (0,0,0). Can someone explain if this is wrong.

    Um, (1,0,0) also satisfies the equation. Describe the other points that do.

    Surely you know "if AB= 0 then either A= 0 or B= 0 or both".
