Lumbar spondylosis is a spine condition that describes the natural deterioration of the lower spine due to age and compression. While spondylosis can occur throughout the spine, the most common location of occurrence is in the lowest portion of the spine, where the lumbar spine meets the sacrum, or tailbone.
A point {lat,lon} is a distance d out on the tc radial from point 1 if: 1  lat=asin(sin(lat1)*cos(d)+cos(lat1)*sin(d)*cos(tc)) IF (cos(lat)=0) lon=lon1 // endpoint a pole ELSE lon=mod(lon1-asin(sin(tc)*sin(d)/cos(lat))+pi,2*pi)-pi ENDIF.
The Distance Formula (page 1 of 2). The Distance Formula is a variant of the Pythagorean Theorem that you used back in geometry. Here's how we get from the one to the other: Suppose you're given the two points (2, 1) and (1, 5) , and they want you to find out how far apart they are. The points look like this:
