CATENARY Calculator - Chain curve

With the CATENARY Trigonometric Function Calculator, you can calculate catenary chain curve values. In addition to the response results, the calculator will also plot the selected function. You can choose a ready-made function, e.g. cat(?#X) where for ? you will substitute e.g. 2 for catenary two which will be equal to 2*cosh(x/2) or enter your own function e.g. cat(2#x^2) for 2*cosh((x^2)/2), cat(2#x+3) for 2*cosh((x+3)/2) etc.
