- | **2.** Perform the integration step of the Green's function solution for the stretched string example given in class. I suggest performing the integration numerically (on a computer). Plot both your numerical result and the exact solution. The form of the exact solution should be calculated analytically (pen & paper, show your working). | + | **2.** Perform the integration step of the Green's function solution for the stretched string example given in class.

It is possible to compute the Green's function integral analytically, or you can solve the inhomogeneous ODE with some other analytical approach. |
