I'm trying to figure out how to show that the limit of a function of two or more variables does not exist. I know that to do this we must show that the limit from 2 different pathways is not equal to the same thing, but, I want to know how to figure out what pathways to check, assuming you aren't using a graphing tool.
Similarly, how can we guarantee that all paths go to the same number and thereby show that the limit exists?
