Paging nruddock!  :lol:

Looking into the catenary problem again, I came across this:

A Brief Exposition Of The Catenary Curve

While I can read very basic summation notation, this is a bit beyond me.  :blink:  :lol:  However, the paper gives a formula which the writer seems to state will allow for the solution of a catenary when the endpoints are not level on Y. 

Quote - Although our figure shows the end-points at the same height, this is not necessary.
Indeed we could place the end-points anywhere on a given catenary curve,
snip the excess, and the resulting portion of the curve would hang unchanged. Put
differently, every part of a catenary curve is also a catenary curve.

Can you make heads or tails of this?  Might this help solve the problem?
