Your question is a bit confusing, but here's some about the coordinate systems:\r
\n" ); document.write( "\n" ); document.write( "Cartesian are square like. Pick an arbitrary point and call that 0,0,0. From there, you can go left / right, up / down, or front / back. The amount of each would be the directions of x , y , z. Generally, + x is right, + y is up, and +z is coming toward you.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Polar coordinates also need an arbitrary point, but deal with that point in relation to a sphere. It needs a r, theta, and phi. The r is the distance from that point (like a radius), the theta is the angle with respect to a line cutting that point, where 0 degrees is generally due right of the picture. Phi does the same concept, but perpendicular to theta.\r
