ABSTRACT

Figures 9-17 and 9-18 show the graphs produced by the above program. It is instructive to rerun this example using, say, 256 and 1024 points, rather than our 512, to get a feel for the effect of changing n. This is left for the end-of-chapter problems, but you would find that the results are only slightly different, since even 256 points give a good "sample" of our rather smooth periodic function, not missing any of its "wiggles."
