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.
Calculating one-dimensional distance between two points when you know the value for each is a cinch. Simply use the formula d = |x2 - x1| . In this formula, you subtract x 1 from x 2, then take the absolute value of your answer to find the distance between x 1 and x 2.Typically, you'll want to use the one-dimensional distance formula when your two points lie on a number line or axis.1  Note that this formula uses absolute values (the  | |  symbols).imply use the formula d = â((x2 - x1)2 + (y2 - y1)2) . In this formula, you subtract the two x coordinates, square the result, subtract the y coordinates, square the result, then add the two intermediate results together and take the square root to find the distance between your two points.
