Question
how do you find the distance from (2,1,2) to the orgin of a 3-d figure?

Answer
The answer is not always findable, but the way to do it it have x(t), y(t), and z(t) where t starts at the origin and ends at x=2, y=1, and z=2.  Note that the t value needs to be the same (t1) at all of these points for the curve to pass through (2,1,2).  The equation is then the integral from 0 to t1 of the squareroot of (x^2(t) + y^2(t) + z^2(t)) dt.
