Maple - Explicit Set Definition & Natural Number Symbol

  1. Oct 31, 2016 #1
    Hi,

    I would like to know if is possible define a set rule explicitly.

    ex.:
    Define the set A explicitly where ξ = ℕ and A = {x | x < 3}.
    The maplesoft said the (N) is a representation of Natural Numbers.



    f:=proc()
    local a,b;
    a:=N;
    b:= 3;
    print(a<b);

    end proc;



    when I called a function f() the result is N < 3

    How can I do to print the real numbers defined above? Is it possible define a set rule like above (like showed in books)?

    Other exemple that I´m trying to get a boolean result is:



    f:=proc()
    local a,b;
    a:=N;
    b:= 3;
    b in a;
    end proc;



    when I called a function f() the result is b ∈ a (I expect "true" or "false").

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
