The curve in which a uniform wire or rope hangs under its own weight is called a catenary. An example of a catenary that we see every day is a wire strung between utility poles, as shown in Fig. 13.20. For a particular wire, the equation of the catenary it forms is y = 2(e^x/4 + e^−x/4), where (x, y) is a point on the curve. Find x for y = 5.8 m.
