The expression type(e, 'equationlist') returns the value true if the expression e is a list of equations, and returns the value false otherwise. It is a synonym for list(equation).

The expression type(e, 'equationset') returns the value true if the expression e is a set of equations, and returns the value false otherwise. It is a synonym for set(equation).

type/list is supertype of equationlist

type/set is supertype of equationset

The type/equationlist and type/equationset commands were introduced in Maple 2022.
