| 2015-09-11 19:19:33 +0200 | asked a question | Possible error in Sage Dear all, while trying to calculate the integral of: integrate (xe^(2x-(x^2)/2), x) I got this: 1/2Isqrt(2)(-2Isqrt(pi)(x - 2)(erf(sqrt(1/2)sqrt((x - 2)^2)) - 1)/sqrt((x - 2)^2) + Isqrt(2)e^(-1/2(x - 2)^2))e^2 Which is actually wrong. The answer is simply e^x² Cheers Sergio |
