Consider the continuous two-dimensional heat transfer in a solid bar with a rectangular cross-section, as shown in the figure. At selected nodes of the outer surfaces, the measured temperatures are seen in the figure. The thermal conductivity of the body is given as follows in two different ways, and there is no heat generation inside the body.

It is divided into 6 equal parts, which are and as in the rectangular shape. Find the temperature of the determined points in the environment using the finite difference method. (Points 1, 2, 3 and 4)
