How do you plot 1/x in the range {x,0,5}? As at x=0, there occurs a singularity in the function. Is it possible to plot this type of function near the x=0 limit?

  • $\begingroup$ What do you mean by plotting it near the limit?? You can use Plot[1/x, {x, 0, 5}] or even with range {x,-1,1} and you'll get a plot that hides diverging parts. When you set PlotRange to All you'll get big values. I can't imagine what would you like to see on that graph as it's only a function getting bigger and bigger as x tends to zero. $\endgroup$ – user16320 Sep 18 '15 at 9:53

    $\begingroup$ Try Plot[1/x, {x, -5, 5}, Frame -> True, Axes -> False] $\endgroup$ – user9660 Sep 18 '15 at 9:54

Of course, you'll never be able to plot this function entirely, it is, after all, diverging to infinity. But maybe this will also be of help:

 Plot[1/x, {x, 0, 5}, PlotRange -> {{-1, 5.5}, {-i/10, i}}],
 {i, {10, 100, 1000}}]


Not really much to see, is there?

PS Please do excuse my working with non-standard options set for Plot at the moment.


You can plot near the singularity by using

Plot[1/x, {x, 0, 5}, Exclusions -> 0]
