    How do you represent an undefined point on a graph? For example, y = sin(x) / x tends towards y - > 1 for x -> 0, but at 0 the function is undefined. Just curious about how this should be represented on a graph.

    Normally you just draw a little circle where the undefined point is to represent that the function is not defined at that point.
