I recently came across a question which was (at least by my reading) just asking for verification of the value of a limit, and the asker claimed to be pretty sure of their answer already.
I'm fairly comfortable with questions asking about how to start with such a limit, or for a more formal proof, or even justifications of motivation / "how should I start with this?", and so on. However, if the asker appears to simply be seeking verification of their answer, I wonder if it's appropriate to refer them to WA or a comparable automated system?
The reason I ask is that, given the circumstances, whilst a proper answer can be given, justifying the steps and so on, that's not really what the asker is looking for - and if I were to give the answer I think the asker is truly looking for, it would be something as brief as "the limit is $\cos(1)$", which seems ...silly. Furthermore, the fact that they're asking for verification on a relatively mechanical question might imply (at least to me) that they're not aware of the existence of automated systems which allow them to check their solutions.
I'm also willing to back down on the specific question - I wouldn't say it was completely unambiguously a "tell me if I'm right" question, by any means - but in the case that such a question is asked, I'd like to know whether it's appropriate to refer them to / at least alert them to the existence of WA.
