"Giulio, your definition is great!! However I think the intention behind kho's original post wasn't simply to make a catenary, but to be able to make a catenary based on both a height and a span as inputs. This is something I wish I knew…"

"I remember http://www.mathhelpforum.com/math-help/calculus/96398-catenary-cable-different-heights.html was a good thread. Maybe you can find some answers there."

"kho, what you are asking for is really the answer to an algebra problem, not a grasshopper problem. You will probably find more help if you ask this question on an algebra forum somewhere."

"Hi kho, here is a C# scripting component calculating points of the catenary curve given a line in 3d space and a length. I also posted it here. It solves the variable numerically. You can see and modify the code. By changing the sign of…"

"i'm writing a FORTRAN programme to calculate the length of required cable and the maximum tension in cable, at support point. The cable is in a catenary curve, suspended from two towers of equal height. so i need the ouput, c to be on the LHS…"

"One way to determine the value of c would be to re-arrange it so that all the terms are on the left hand side, ie c-c*cosh(L/2c)+H=0. Then incorporate the LHS into a function component with c as a slider input. Then manipulate the value coming out…"

"i'm using this formula to calculate the catenary constant, c. c + H = c*cosh (L/2c), where, c = catenary constant H = maximum sag L = span I need to manipulate the equation in such a manner that c is the subject of the equation, in terms of…"

"hi kho, I just used this catenary formula, from wikipedia: y=a*cosh(x/a) a was an input from a slider, and by changing it, the height of the catenary is adjusted x was an input based upon distance along a line y was the output. so when I wrote…"
