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.
Distance Formula. The distance between (x1, y1) and (x2, y2) is given by: `d=sqrt((x_2-x_1)^2+(y_2-y_1)^2`. Note: Don't worry about which point you choose for (x 1, y 1) (it can be the first or second point given), because the answer works out the same.
