Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to get the partial derivative of the following with respect to Si[t] and Phi[t] separately:

Integrate[<Phi[t]|H|Si[t]>]

The operator H is the partial derivative with respect to t.

I tried this in Mathematica, calling

Needs["Quantum`Notation`"]

but I end up with an strange term : " zz080Bra' "

Any help and advice in this line is appreciated.
