1.Develop a computer code for the solution of a one-dimensional diffuse equation in a plane slab of thickness L. The code generates the element characteristic equation and forms the global system of equations based on the linear line element. Solve the system of equations using the Gauss-elimination solver. Use the code for the solution of the problem.

2.Derive the element characteristic equation starting from Equation 11.10 and using the quadratic line element defined.
