You may be interested in these slides from a lecture (yet more information to consume) on how to find answers to grad level math like using oeis.org to identify sequences, where to post on stack exchange/mathoverflow to get answers, using the inverse symbolic calculator ect http://www.cs.cmu.edu/~15751/2016-lecture1.pdf

That lecture drastically reduced the time I spend now finding answers which usually I found myself drifting into the attention economy while I stopped working to search for things.
