Abstrakt:	In rare cases, the use of advanced mathematical calculators can give incorrect results. One such error occurs with graphing calculators because the screen is not continuous, but a rectangular array of pixels. On some frequently used calculators, the graph of sin?80x looks like sin?x. We also study other related examples. [ABSTRACT FROM AUTHOR]
