A machine contains the grid of wires shown in the accompanying sketch. At the seven indicated points, the temperature is kept fixed at the given values (in C). Consider the temperatures T\ (/), 72(0, and T^(t) at the other three mesh points. Because of heat flow along the wires, the temperatures 7/ (0 changes according to the formulaTi(t + 1) = 7)0) - -L (7 )(/) - radj(0).where the sum is taken over the four adjacent points in the grid and time is measured in minutes. For example,r2(r + 1) = r2(o - jjj(r2
