The best way to set F2 as the derivative of F1 is to do, in CAS:
F2:=F1' quick and easy...

F2 should be d(F1(X)/X=X)...

Stuff in functions should evaluate to a number when X is a number... X² evaluates to a number...
BUT, d(F1(X)/X) evaluates to a function (of X), NOT a number!!!!
d(F1(X)/X)|X=X or, as a shortcut syntax, d(F1(X)/X=X) does evaluate to a number...

We have put some hacks in place to make is as user friendly as possible, but it's not perfect.

hacks?
one recursive evaluation?
or
