Figure 1. Comparison of the accurate solution $q\left(x\right)$ and the corresponding approximate solution $q_{est}$ for h=0.1 and $N_0=2000$ with the nodal subset $\{x_{N_0,0}^j{\}}_{j=500}^{2000}$.

Figure 2. Comparison of the accurate solution $q\left(x\right)$ and the corresponding approximate solution $q_{est}$ for h=0.005 and $N_0=10000$ with the nodal subset $\{x_{N_0,0}^j{\}}_{j=2500}^{10000}$.
