324 | * <h4>Explanation:</h4>
|

325 | * We get an isosceles triangle with the center of the Earth and the 2

|
||
327 | * triangles. We know two values, the angle of 1 grade, that will be 0.50
|

328 | * grades in each triangle, and the Earth radius that is the hypotenuse.
|
||
329 | * Then we apply trigonometry and get the distance <i>D</i> between both
|
||
330 | * points on the Earth surface.</p>
|
