Problem with latest XKCD
One of the numbers asked for in the latest XKCD is the integral from 0 to pi of x*sin^2 x.
https://xkcd.com/2966/ Explain xkcd says the answer is pi^2/4 or 2.4674... https://www.explainxkcd.com/wiki/index.php/Main_Page I tried with the HP71: Integral(0, pi, 1e-12, Ivar*sin(Ivar)*sin(Ivar)) = .007413.. The prime in cas mode gives an error |
