(x1, y1, z1) and (x2, y2, z2) are the coordinates of the two points. Results using the haversine formula may have an error of up to 0.5% because the Earth is not a perfect sphere, but an ellipsoid with a radius of 6,378 km (3,963 mi) at the equator and a radius of 6,357 km (3,950 mi) at a pole. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. Note that neither the haversine formula nor Lambert's formula provides an exact distance because it is not possible to account for every irregularity on the surface of the Earth. Or was there some mistake that resulted in a negative distance from the point to the plane? 13th Edition. @-@ (confused face), distance should be seen in absolute terms there is no direction to it, d is the smallest distance between the point (x0,y0,z0) and the plane. 0000102915 00000 n think about that a little bit. 0000014256 00000 n is three right over here.
