Yes, as Robert Dodier wrote, I wish to get a web application witch
differentiates function in small short steps. The draft version is on
http://wood.mendelu.cz/math/maw/derivace/derivace.html (this link changes in
future).
I wish to prevent expansion of (sin(3x+x^2))'=cos(3x+x^2) *
(3*(x)'+(x^2)')
since the step (sin(3x+x^2))'=cos(3x+x^2) * (3x+x^2)' is skipped.
As I wrote, I have a draft version of this application, but I am not fully
satisfied with the result and I will try the hints from this discussion
group. So thank you for your answers.
