Question:
Using the Galerkin method, solve the following differential equation with the approximate solution in the form of \(\tilde{u}(x)=c_{1} x+c_{2} x^{2}\). Compare the approximate solution with the exact one by plotting them on a graph. Also, compare the derivatives \(\mathrm{d} u / \mathrm{d} x\) and \(\mathrm{d} \tilde{u} / \mathrm{d} x\).
