“As viral puzzles became popular, mathematicians joined the game too. Here’s a fun puzzle that has been widely shared.”
minus-squareParsniplink2•1 year agoI don’t think that would work. You just use the fact that the integral from negative to positive infinity of sin(x)/x is pi, so from 0 to infinity it is pi/2, which you can derive from using Feynman’s trick for computing weird integrals like these.
