GPT4 with WolframAlpha plugin even gave me enough information to implement Taylor polynomial approximation for Gaussian function (don't ask why I needed that), which would have otherwise taken me hours of studying if I could even solve it at all.
PS: GPT4 somehow knows even things that are really hard to find online. I recently needed standard error but not of mean but rather of standard deviation. GPT4 not only understood my vague query but gave me formula that is really hard to find online even if you already know the keywords. I know it's hard to find, because I went ahead to double-check ChatGPT's answer via search.
Good luck when you need to update it and adjust it - this is the equivalent than copying/pasting a function from Stack Overflow.
i find it most helpful when i am not sure how to phrase a query so that direct search would find something. but i also found that in at least half the cases the answer is incomplete or even wrong.
the last one i remember explained in the text what functions or settings i could use in the text, but the code example that it presented did not do what the text suggested. it really drove home the point that these are just haphazardly assembled responses that sometimes get things right by pure chance.
with questions like yours i would be very careful to verify that the solution is actually correct.
But now I'm curious!
And you face the same problem when looking for something in a domain you are not an expert in - no way to tell if a web page is truthful and no way to tell if ChatGPT is right. ChatGPT just lets you make more mistakes more efficiently.
But for those cases where you kind of know the answer, ChatGPT is usually better than search.
With a regular search engine you've already found your answer by that time.
