It can be generated by rolling the focus of a parabola along a straight line. If its lowest point is placed on the origin, it can be graphically described by the equation y equals c times the hyperbolic cosine of x over c. FTP, identify this curve that can also be represented by letting a piece of string hang freely between two fixed points.
