- If i,j, and k are the unit vectors along the 3 axes, and t is some
- parameter, call the first vector r1 and the 2nd r2.
-
- Then find r3 = r1 - r2 by subtracting the components.
-
- Let r3(i), i = 1,2,3 be the 3 components of r3. The distance between the
- vectors r1 and r2 is
-
- d = sqrt[r3(1)^2 + r3(2)^2 + r3(3)^2]
