Consider steady two-dimensional heat transfer re In a rectangular cross section (60 cm ×30 cm) with the prescribed temperatures at the left, right and bottom surfaces to be 0°C, and the top surface is given as 100sin(лx/60) .Using a uniform Δx = Δy, determine (a) the finite difference equations and (b) the nodal temperatures
