If two faces of the slab 0Sx <L are kept at temperature zero, and the initial temperature of the slab is given by u(x, 0) = A (a constant) for 0<x< u(x, 0) = 0 for <x<L. Then the formal series solution u(x. e sin 2| Hat 4 -n²x*xt exp плх Two iron slabs are each 20 cm thick. Initially one is at temperature 500°C throughout and the other is at termperature 0°C. At time t=0 they are placed face to face, and their outer faces are sin kept at 0°C.
