When a flexible cable of uniform density is suspended between two fixed points and hangs of its own weight, the shape y = f(x) of the cable must satisfy a differential equation of the form

Where is a positive constant. Consider the cable shown in the figure.
(a) let z = dy/dx in the differential equation. Solve the resulting first-order differential equation (in z), and then integrate to find y.
(b) Determine the length of the cable.
