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

in the Sage 9.0.beta2 I get [ipython-5.8.0] Successfully installed ipython-5.8.0 [ipython-5.8.0] Cleaning up... [ipython-5.8.0] Removed build tracker '/tmp/pip-req-tracker-h6h22jg5' [ipython-5.8.0] [ipython-5.8.0] real 0m2.424s [ipython-5.8.0] user 0m2.136s [ipython-5.8.0] sys 0m0.398s

[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

Inspired by this ask.sagemath question . Minimal case is sage: f=function("f") sage: F(x)=integrate(f(t),t,0,x) sage: diff(F(x),x) --- AttributeError
