$2.$ The steody state temperature distribution u $(x,y)$ in a thin, homogenous semi$-$infinite plate is goveened by the boundary value problem

$\frac{de{l}^{2}a}{del{x}^2}+\frac{de{l}^{2}z}{de{l}^2}=0,00$;$(\frac{\text{d}\text{e}\text{l}\text{v}}{\text{d}\text{e}\text{l}\text{y}})(x,0)=0,00$

Find the temperature distribution $u(x,y),00.$
