The steady heat diffusion equation $$T$=0$ is solved in two space dimensions with the finite difference method on a uniform grid.The points T$2,$T$3$ and T$4$ lie on an adiabatic boundary. For $$x$=0\mathrm{.}02$m and $$y$=0\mathrm{.}02$m$,$ evaluate the value of T$3($in oC$)$ to one decimal place accuracy $(+-0\mathrm{.}1)$
