Thanks a lot ! That's perfectly clear... Any hints on how to file a ticket for this issue ? Le vendredi 25 octobre 2019 10:20:26 UTC+2, Nils Bruin a écrit : > > Yes, that's a bug. It happens in F(x).operator()._tderivative_ It > differentiates the bounds in case those vary with the

[sage-support] Re: Possible bug in integrate ?

Yes, that's a bug. It happens in F(x).operator()._tderivative_ It differentiates the bounds in case those vary with the differentiation variable, and that does not work for "0". If you define var('y') F(x)=integrate(f(t),y,x) you get the right result (with y not being a function of t). The
