    1)I use Linux Mint 17.2 and wxMaxima 13.04.2. In wxMaxima 13.04.2, the code below, It plays correctly:
    plot2d([x,x^3,[discrete,[[0,0],[1,1],[-1,-1]]]],[x,-5,5],[y,-5,5],
    [style,[lines,2,1],[lines,2,4],[points,3,2]],[point_type,bullet],
    [legend,"x","x^2",""],[xlabel, "x"], [ylabel, "y"],[label,["A(1,1)",1.2,1],["O(0,0)",0.1,-0.1],["C(-1,-1)",-1,-1]],
    grid2d,[ytics, 0,1,3], [xtics, 0, 1, 3],
    [title, "Graphic"],[axes, solid]),
    plot_size=[500,500];

    On http://maxima-online.org/ ,I receive many errors for this code. Why?
    Thanks.


    2)How do I verify that the result of product prod(1-1/(k^2),k,2,n) is (n+1)/(2*n)?

    is(prod(1-1/(k^2),k,2,n)=(n+1)/(2*n));
    false
    Why?

    3)I use wxMaxima 13.04.2 on Linux Mint 17.2. When I type the command:

    A:matrix([1,2,3],[4,5,6],[7,8,8]);invert(A);

    the answer is:

    Maxima-online.org and Maxima on Android not have this issue.
    Thanks.

    Thanks for the post! 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?
