[Suggestion] A function that returns undefined points/lines for any given equation

[niek-peters]

I think it would be really helpful to have a way to know beforehand which variable values in an equation will result in undefined points or asymptotes, without having to bruteforce many different values to test for such things.

It could be done by checking for possible devides by 0 and with a list of possible undefined results for different mathematical functions.

Or is there already a way to achieve this with the current nerdamer?

Interesting. There is no such functionality in Nerdamer today that I know of. Bits and pieces are there, such as the Newton solver looking for sign-changes and assessing whether 0 is an output or whether it is looking at an asymptote. But the approach here would have to go inside out, from 0-denominators and known undefined points of functions.
