Show me how to draw Catenary curves

[Guest_imported]

How do you draw catenary curves. (These are the shapes made by a cable or rope strung between two anchor points). The equation of the catenary is
y= a cosh(x/a)-b

type in CIRCLE in QB and press F1 for help. It's there, just read it.




English is too hard to learn, the vowles change too much like come/home, comb/tomb, book/school, high/bye/sty, etc., etc. So should I say Geez or Sheez or Cheeze? hehe.

replace the equation y=e^x with

a = 2.2 'change this to whatever you want
b = 2.6 'change this to whatever you want
Y = a * cosh(x / a) - b
