Please explain it thoroughly. 1D string and heat conductor Problem 1.1. (4 pts) Consider the 1D vibrating string equation ch.. (t,x) = hn(t,x) + fh(t,z), x E [0, L], f > 0 with the boundary condition h(t,0-0, hz(t, L)=0. Write the most general solution and discuss the qualitative behaviour of the solution (especially its depen- dence on t), can you give a physical interpretation to the f-term? Problem 1.2. (2 pts) Continuing from the above exercise. Now add the initial...
