As a non-mathematician I'm confused by this Wikipedia article. Isn't it trivial to fabricate arbitrarily hard integrals by starting from a function with known values and differentiating it?
I understand that people enjoyed the prank, but I think the article doesn't make it clear enough that he was just trolling and wasn't actually solving hard mathematical problems
