Access to an element



  • How get I access to an element of a list? Below you see the code for evaluating a plane. The last element is the solution I am looking for. But, how can a separate this solution?

    $TA=maple("
    geom3d[point](P1,[5,2,1]),
    geom3d[point](P2,[4,0,-4]),
    geom3d[point](P3,[1,1,1]),
    geom3d[plane](E1,[P1,P2,P3]),
    geom3d[Equation](E1,[x,y,z]);

    ");

    $LE=maple("$TA[5]"); #no access to element 5 why???
