Suppose we have a rod of material of conductivity K = 1
and situated on the x-axis, for 0 ≤ x ≤ 1. Suppose further that the rod is
laterally insulated, but has a known internal heat source f(x). The left and
right ends of the rod are held at 0 ◦C (degrees Celsius). With n = 5
Solve the linear system in Jupyter using Gauss-Jordan Elimination. See the notes on
the first problem of this set for hints on how to use and report the results from Gauss-Jordan Elimination.
This equation can be
understood as balancing the flow of heat from a node to its neighbors:
−yi−1 + 2yi − yi+1 = h2/k f(xi)

We have a metal rod of length L. The rod is on the x-axis extending from 0 to L. We select a point X on the rod randomly and uniformly and cut the rod at X. This gives two smaller rods of lengths X and L − X. We select the longer piece (if the two pieces are of equal length we select one of them) and cut it again randomly and uniformly to get three pieces. What is the...
