I suppose that you mean df(sin(x))/d(sin(x)), and yes. ``Derivative(f(sin(x)), sin(x))`` will be allowed. However, since ``dx/d(sin(x)) != 1/(d(sin(x))/dx)``, evaluating this will result ``Subs`` instance, I guess.
Mistyping issue will be prevented by introducing 'rigorous' variable, as I mentioned above. And frankly speaking, it's user's fault if one mistypes the input. 2020년 1월 5일 일요일 오전 2시 22분 8초 UTC+9, David Bailey 님의 말: > > On 04/01/2020 13:08, mcpl snu wrote: > > It's same as df(t)/dt, where t=x+1. > > Thanks, and I suppose that also generalises to expressions such as > df(x)/d(sin(x))? > > df(t)/dt where t=sin(x) > > Given how easy it is to mistype input to sympy, I don't think such an > extension is such a good idea. > > David > -- You received this message because you are subscribed to the Google Groups "sympy" group.
