A cable hangs between two poles of equal height and 30 feet apart. Set up a coordinate system where the poles are placed at x=-15 and x=15, where x is measured in feet. The height (in feet) of the cable at position x is

h (x) = 14cosh (x/14)

cosh (x) = (e^x+e^-x) / 2 i

I don't know how to explain this, I'm really bad at it!
