4. Any cable hanging between two poles must follow a specific curve. To simplify calculations, we choose a coordinate system so that the locations of the two poles are at x = -B and x=+B. The curve has equation y = C + A cosh(). Find an integral expression for the length of the cable, and evaluate that integral. (Your final answer will be in terms of A and B.)
