Hello,
*Problem:* Sage 6.7 returns for integrate(x/(x^2+1),(x,0,infinity)) the result 0. This is obviously wrong, since x/(x^2+1) is positive betwwen 0 and Infinity. *What I found out by now:* I couldn't reproduce the error with any simpler function. The antiderivate of the function is calculated correctly with integrate(x/(x^2+1),x) as 1/2*log(x^2 + 1). Manualy entering the values 0 and Infinity there gives the correct result. What should I do now? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
