Using version 4.1, Integral[Sin[x+d]/(x+d),{x,-Infinity,Infinity}] yields 0 . This is, of course, incorrect. (Does version 4.2 make this error also?) Mathematica does Integral[Sin[x]/x,{x,-Infinity,Infinity}] correctly however, yielding Pi, which should also be the answer for the original integral (regardless of the value of d). Does anyone have an idea why Mathematica gets the original integral wrong?
