**Problem 4.4a.** Produce a BVP for the Laplace equation, describing the equilibrium heat distribution in a thin square block \(0 \leq x, y \leq L\) [m], with insulated square sides. Denote the temperature of every point of the block by \(u(x, y)\) [°C]. The sides of the block are maintained at the following temperatures: the sides \(x = L, y = 0,\) and \(y = L,\) at \(u = 0\)°C. The side \(x = 0\), at temperature \(u = \begin{cases} 
\frac{y}{100}, & 0 \leq y \leq L/2, \\
\frac{L}{100} - \frac{y}{100}, & L/2 < y \leq L. 
\end{cases}\) [°C].  
Provide a sketch.
