High School Hypothetical 3 Dimensional Coordinates

Click For Summary
SUMMARY

The discussion centers on the conversion of spherical coordinates to rectangular coordinates, specifically analyzing the equations x = rsinθcosφ, y = rsinθsinφ, z = rcosθ and x = rsinθcosφ, y = rsinθsinφ, z = rcosθsinφ. The first set of coordinates represents a sphere, while the second set does not represent a standard geometric shape. The correct interpretation of spherical coordinates involves using the Greek letter rho (##\rho##) to denote the radial distance.

PREREQUISITES
  • Spherical coordinates and their conversion to rectangular coordinates

If the coordinates

x = rsinθcosφ, y = rsinθsinφ, z = rcosθ

represent a Sphere, then what does the coordinates

x = rsinθcosφ, y = rsinθsinφ, z = rcosθsinφ

represent?

No, they don't. These are just the conversion formulas for converting from spherical coordinates to rectangular coordinates. (Although r should be ##\rho##, the Greek letter rho.)

In spherical coordinates, the equation of a sphere is very simple: ##\rho = k##.

You might try combining the first and second equations (by squaring each side) and the second and third equations (doing the same thing), to get an equation in x,y, and z alone.

Mod note: Thread moved, as this is more of a general question than one concerned with topology or analysis.
