Final answer:
Rectangular coordinates for London, England in a geocentric coordinate system can be calculated using its latitude and longitude along with the Earth's radius.
Step-by-step explanation:
The geographic coordinate system uses latitude and longitude to locate any point on Earth. London, England's coordinates are specified by its latitude of 51° 32' N and longitude of 0° 5' W. Assuming the earth as a sphere with a radius of 6367 km, the rectangular coordinates of London in a system with the origin at the center of the Earth can be calculated. Since these calculations involve spherical to Cartesian coordinate conversion, they require trigonometric functions to determine the x, y, and z values based on London's latitude and longitude.
