the graph. Here are two functions whose behaviors are interesting to see
graphically. One of them is sin(1/x) whose graph keeps oscillating infinetely
often as x appproaches 0. By zooming in, you'll see that the graph has the same
behavior as x goes to 0. Also, it proves that this function is not continuous in
0. Another interesting function would be IntegerPart(1/x) that illustrates the
local linearity i.e. no matter which point of the graph you choose to zoom in
on, the curved line ends up looking like a horizontal line. For some reason I
wasn't able to graph the last one.
