![]() The backward conversion has similar domain restrictions for the spherical coordinates. To convert from spherical coordinates to Cartesian coordinates: To convert from three-dimensional Cartesian coordinates (x, y, z) to spherical coordinates (r, θ, φ), use the following formulas: Spherical Coordinates: Convert to and from Cartesian The performance tests would show how balanced or distorted sound pressure distributions and sound waves are detected by human ears (Kerscher, 2010). Simple tests for frequency levels (in Hertz) uses spherical coordinates to visualize frequency performance. The application use for spherical coordinates was found useful within the sound industry specifically, for mapping frequency patterns. The name change expresses how far above the equator and how far across from the prime meridian a point is, geographically speaking. The naming of the polar angle and azimuthal angle gets changed to latitude and longitude. Real-World Applicationįor a coordinate system that describes a point through spherical references, the spherical coordinate system is widely used to map exact points on Earth. However, the visualization of higher-dimensional coordinate systems is limited to graphical approximations and word descriptions. The spherical coordinate system can be extended to dimensional spaces higher than the third dimension, referred to as the Hyperspherical Coordinate System. *The azimuthal angle is preferred to be positive to follow the positive counterclockwise direction (similar to what occurs in the unit circle). The azimuthal angle* to be in degrees or radians of limitation from 0 to 360° or 2π rad.The polar angle to be in degrees or radians of limitation from 0 to 180° or π rad.All distance length of r is kept as a positive number.However, both the naming of the systems and the process in getting to that coordinate differs. The exact placement of the spherical coordinate matches that of the Cartesian coordinate. Azimuthal Angle is the angle made from reflecting off the x-axis and revolves on the x-y plane.Polar Angle is the angle made from reflecting off the z-axis.Radial Distance is made from the origin point.The referencing for each spherical coordinate (r, θ, φ) is based on the z-axis, where: Z-coordinate replaced by Azimuthal Angle ( φ).Y-coordinate replaced by Polar Angle (θ).X-coordinate replaced by Radial distance (r).The Spherical Coordinate System replaces the x, y, and z Cartesian Coordinates with the following: ![]() The system normally uses radians instead of degrees. Spherical Coordinates make up a type of Coordinate System that best suits the description of positions and overall geometry of a sphere.
