my measurement of a six-degree tilt, I can calculate that the tree root has<br/>
moved the center of the brass disc five inches into Texas.  To arrive at this, I<br/>
assumed that the monument pivoted from its bottom end, which would likely have<br/>
stayed put as the top was pushed westward.  To calculate the distance of its<br/>
departure, I multiplied the length of the monument by the sine of its bearing.<br/>
It comes out to almost exactly five inches, which is as accurate as possible<br/>
using a protractor and a hand level to measure the angle.<br/>
