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) = 15 cosh(x/15), where cosh(x) = (e+ e-*)/2 is the hyperbolic cosine, which is an important function in physics and engineering. The cable is feet long
