atan is the normal arc-tangent or inverse tangent function. atan2 - available in many programming languages - takes two parameters (arguments) instead of one, that represent the coordinates of a point. If the coordinates are, for example, (5, 3), the calculation is equivalent to atan(5/3). However, if the point is in other quadrants, the function will return an angle in the correct quadrant. For example, for (-5, -3), it will return an angle in the third quadrant.

How do you change cartesian to spherical coordinates?
float2 CartesianToSpherical(float x, float y, float z) { float2 SphericalPos; SphericalPos.x = atan2(x,z)/6.28318f; if(SphericalPos.x < 0.0f) SphericalPos.x += 1.0f; SphericalPos.y = atan2(sqrt(x*x+z*z),y)/3.14159f; return SphericalPos; }

How does the golden ratio relate to platonic solids?
The golden ratio, phi occurs many places in the platonic solids. The dihedral angle on the dodecahedron is 2*atan(phi), and the dihedral angle on the icosahedron is 2*atan(phi2) or 2*atan(phi + 1). The mid radius of the dodecahedron is similarly phi2/2 or (phi + 1)/2, and the mid radius on the icosahedron is phi/2. There are several other measures within Platonic solids which involve phi.
How is the distance between two rational numbers related to their difference?
Directly. Their difference IS the difference between them.
What is the difference between 9538 and 6743?
The difference is 2,795.
