Select the type of limit: two-sided, left-handed, or right ...Then applying L'Hopital's Rule to get the limit to be 1, however, some other people are saying we can't use L'Hopital's Rule on multivariable limits. My understanding is that we have now separated this limit into two single variable limits so we should be able to use L'Hopital's Rule.Taking the case of a function of two variables, by definition we specify an ϵ>0 that sets the error bound for our function. The corresponding δ value is the ...Finding examples of two different approaches giving different limits (in the case that the limit doesn't exist) is usually easier in the original $(x,y)$ coordinates. The point of polar coordinates (as I see it) is to have a tool for proving that the limit is what you think it is (in the case when the limit exists). $\endgroup$ –This section introduces the formal definition of a limit. Many refer to this as "the epsilon--delta,'' definition, referring to the letters ϵ and δ of the Greek alphabet.
