Equation Modeling the 3D tilt of the Earth

  1. Oct 13, 2009 #1
    The Earth is on a tilted axis. The angle or radial tilt is 23.439281deg. This means the slice thru the center out to 23.439281deg and also extending out thru the center to -23.439281deg. How do you model this in spherical coordinates? I have a 3D Sphere:

    For phi = 0:360
    For theta = 0:360
    x = Rearth*cos(phi)*cos(theta);
    y = Rearth*cos(phi)*sin(theta);
    z = Rearth*sin(phi);
    plot(x,y,z)
    hold on;
    end;
    end;

    What I need is an equation for a slice out of the 3D sphere thru the center at the radial tilt angle, 23.439281deg (It does not have to be a computer program).
