The variable of the polynomial. A string expression.
..., expr2, expr1, expr0
The coefficients of the polynomial. Numeric expressions.
The polynomial displayed using TeX.
The poly(exprX,[..., expr2, expr1, expr0]) function displays in TEX format the polynomial of variable exprX with constant coefficients expr0, expr1, expr2, ..., ordered according to the decreasing powers of exprX.
The corresponding mathematical notation is:
Both the polynomial variable and its coefficients can be defined as global or local variables.
A more general formatting function has been suggested (Moodle quiz forum). This may be implemented in the future.
