Distance Between Two Points
The straight line distance between two points in cartesian coordinates.
Two points given by P1 and P2
Where
d = distance between two points
x1,y1 = cartesian coordinates of point 1
x2,y2 = cartesian coordinates of point 2
This is easily extended to points in three dimensions:
Where
d = distance between two points
x1,y1,z1 = cartesian coordinates of point 1
x2,y2,z2 = cartesian coordinates of point 2
