(%i1) display2d : false $ (%i2) foo : 1/log(x)^2 $ (%i3) integrate (foo, x, 2, 3); (%o3) gamma_incomplete(-1,-log(3))-gamma_incomplete(-1,-log(2)) (%i4) %, numer; (%o4) 1.273097216447114 (%i5) integrate (foo, x); (%o5) gamma_incomplete(-1,-log(x)) (%i6) ev (%, x=3) - ev (%, x=2); (%o6) gamma_incomplete(-1,-log(3))-gamma_incomplete(-1,-log(2)) (%i7) %, numer; (%o7) 1.273097216447114 (%i8) quad_qags (foo, x, 2, 3); (%o8) [1.273097216447114,1.413421842285782E-14,21,0] Looks like Maxima handles the definite and indefinite integrals as expected. Or perhaps I have misunderstood the problem? Hope this helps, Robert Dodier -- You received this message because you are subscribed to the Google Groups "sage-support" group.
