Hi there, I want to compute the integral from 2 to 3 of the funktion f(x)=1/log(x)^2. Sage gives conflicting results for different ways to compute it:
*numerical way* (double checked by Wolfram Alpha <http://www.wolframalpha.com/input/?i=int%20from%202%20to%203%20of%201%2Flog%28x%29^2> and Maple): sage: numerical_integral(1/log(x)^2,2,3) (*1.273097216447114*, 1.4134218422857824e-14) *symbolic way* (I think this is wrong) sage: N(integral(1/log(x)^2,(x,2,3))) *0.536566859259958* The funktion is not that evil in the interval [2,3], so I don't think it is just a numerical issue. This is the minimal example. I am using sage 6.1 and 6.3 (tried both) on Ubuntu. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
