Hello

Quoted expressions ('expression') are not working well in CAS history

F1(x):='sin(x)'; ⇨ 'sin(x)'

[up key] QUOTE(sin(X))

f2(x):=quote(sin(x));

[up key]

f1:=(x)->'sin(x)'

f(x):=x^2;

f(x)' ⇨ 2*x // ok

f' ⇨ (x)->2*x

a/b; ⇨ a/b // ok

quote(a/b); ⇨ a/b (problem, not include quotation marks) ⇨

[up key][up key]copy '(a/b') error ? It's a BUG or not?

Is expected ⇨ quote(a/b) or 'a/b' or '(a/b)'

numer(quote((a/b))) ⇨ a/b

numer(eval(quote((a/b)))) ⇨ a // ok

[up][up]copy error ?

He does not let me retrieve the input

One of the functions of the history is to be able to call inputs and outputs and then manipulate them. Who agrees with this?
