The documentation says: 'factors' gives the list of factors, except for the unit, which can be recovered using 'unit'. Since 'EXPR INT' is a field, everything non-zero is a unit:

\begin{axiom}
unit((sin x)::FR EXPR INT)
\end{axiom}

fricas

(1) -> factors 5

$\label{eq1}\left[{\left[{factor = 5}, \:{exponent = 1}\right]}\right]$

(1)

Type: List(Record(factor: Integer,exponent: NonNegativeInteger?))

but

fricas

factors sin x

$\label{eq2}\left[ \right]$

(2)

Type: List(Record(factor: Expression(Integer),exponent: NonNegativeInteger?))
