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.
Since the distance around the track in lane one, the inside lane, is 400 meters the distance around the track for the other lanes can be calculated by knowing the lane width and a few other measurements. The formula, L = 2S + 2pi(R + (n-1)w) can be used to calculate the distances around the track for the various lanes.
