A round underwater transmission cable consists of a core ofcopper wires surrounded by nonconducting insulation. If x denotesthe ratio of the radius of the core to the thickness of theinsulation, it is known that the speed of the transmission signalis given by the equation y = x2 ln (1/x). If the radius of the coreis 1 cm, what insulation thickness h will allow the greatest transmissionspeed?
