Question: Really real discontinuities.


is it possible to search for only real discontinuities? There is a discont command and you can see in the help that it finds discontinuities over the reals. But it searches also over the complex domain. Can I restrict the command only for the real domain? I tried to use "assuming real", "RealDomain", but nothing works.

You can try the following example function: f := x-> 3/(1-exp(1/x)):

The only real discontinuity is in 0, but the discont command returns also the complex discontinuities.

Please Wait...
