For the rod in 9:(a) Plot u versus x for t = 5, 10, 20, 40, 100, and 200. Put all of the graphs on the sameset of axes and thereby obtain a picture of the way in which the temperature distributionchanges with time.(b) Plot u versus t for x = 5, 10, 15, and 20.(c) Draw a three-dimensional plot of u versus x and t.(d) How long does it take for the entire rod to cool off to a temperature of no more than1C?
