You can also explore eigenvectors, characteristic polynomials, invertible matrices, diagonalization and many other matrix-related topics. In any case, I would not rely on WolframAlpha or Mathematica to handle multivariate limits. Math Input Vectors & Matrices More than just an online eigenvalue calculator WolframAlpha is a great resource for finding the eigenvalues of matrices. While it can handle some special queries, I suspect that these are probably pre-programmed somehow, or that they were special (but common) queries that were added to the knowledge base. calculator - WolframAlpha calculator Natural Language Math Input Use Math Input Mode to directly enter textbook math notation. You get a wrong response, because again, WolframAlpha is built on Mathematica's functionality. Evan Smith Posted 7 years ago Theres an issue with my work network as well. You will get the proper response, but if you enter You can contact with whatever issues you are seeing, steps to reproduce, OS/browser, account information (if applicable), etc. Now, that doesn't mean that WolframAlpha can't be a bit smarter than Mathematica's built in Limit: if you enter

This error definitely shows that such multivariate limits are not within the scope of Mathematica's functionality. x -> y, is not a valid variable for Limit.

Mathematica, and consequently WolframAlpha, does not have built-in capability to evaluate arbitrary multivariate limits.
