Ticket #15504 – Description
v1 v10 1 1 From google spreadsheet which no one reads `X(` 2 2 3 A simple integration error.4 3 {{{ 5 4 sage: integrate(log(1+x)/x,x) … … 9 8 }}} 10 9 11 Both of which are wrong according to 2.728 of Gradshteyn & Ryzhik. Actually the second example is obviously wrong since the integration is a real function over a real interval. 12 13 Should I report the error to Maxima? That seems to be the source. 14 15 PS: 16 1. The "I" above is not me (ppurka) 17 2. I am done scrounging through the google spreadsheet for bugs, for now. 10 Since `dilog(2) = pi^2/4+log(2)^2/21/2*(log(2)+I*pi)^2` the result is simply `pi^2/12`.
