Some reasons probably are: |

* using a different (mean) radius of the earth |
|||
* using a derived radius from the earth's circumference |
|||
* use of difference precisions |

* use of different formulas for trigonometric functions |

Different results
I find it interesting that there are two 'clusters' of results around 2886.4 and 2887.26 with very few 'significantly' differing ones- Now: who is 'correct' here ??? and why are so many others 'wrong'??? --Walterpachl 19:08, 16 August 2012 (UTC)
2886 km (1793 miles) 2886.326609413624 2886.327 2886.4 km 2886.44 2886.44 kilometers (or 1793.55 miles) 2886.44444099822 2886.444442837984 2886.44444 2886.4 2887 km. 2887.2599 km 2887.2599506071097 2887.25995060711 2887.2599506071106 2887.2599506071106 2887.2599506071106 2887.259950607113 2887.25995060711 2887.26 km. 2887.26 km. 2887.260 km. 2887.2600 km 2887.26 2887.3 km (1794.1 mi.) 2887.3 km 2889.68
- This might be due to the different values given for the rough radius of the Earth, in kilometers, for different examples. --Paddy3118 19:22, 16 August 2012 (UTC)
Some reasons probably are:
- using a different (mean) radius of the earth
- using a derived radius from the earth's circumference
- use of difference precisions
- use of different formulas for trigonometric functions
