EX3: Non-Constant Conductivity I

Problem 49:

It is of interest to see how the shape of the graph of the solution (5.6) found in Problem 5.2 depends on the sign of . Suppose = 300 K, = 500 K, = 1m, = 80.2 W/mK.

For each of the values , , , find from equation (5.4), then plot (5.6) on the closed interval . (The conductivity relation for iron is well approximated by (5.1) when , , .) What qualitative differences do you observe among these curves?
