Cheers, Michael Re: HP-Prime Polynomials: User Guide and Request - CompSystems - 09-27-2013 Nuevo lanzamiento Version 0.0.3, con muchas mejoras, en redacción permanente hay un problema con diff, e int cuando la expresión es un polinomio como arreglo diff(poly1[1,-4,4],x) => [ 0, 0, 0 ] ??? espero que se solucione pronto, la salida correcta es poly1[2,-4] Edited: 28 Sept 2013, 12:29 p.m. after one or more responses were posted Re: HP-Prime Polynomials: User Guide and Request - CompSystems - 09-28-2013 Nuevo lanzamiento Version 0.0.5 hay unos posibles BUGs, espero que TIM me ratifique o no los BUGs Composicion con polinomios p(x) := x²+1; p1(x) := x+3; p(p1(x)); => x²+6*x+10 // OK but p(x) := poly1[ 1, 0, 1 ] p1(x) := poly1[ 1, 3 ] p(p1(x)); => poly1[ 1, 0, 1 ] // BUG? diff(x²-4*x+4,x); => 2*x-4 diff( poly1[1,-4,4],x); => [ 0, 0, 0 ] // BUG? int([1,-4,4],x); => [ 0, 0, 0 ] // OK int(x²-4*x+4,x); => (x^3/3)-(4*x²/2)+4*x int(poly1[1,-4,4],x); => [x,-4*x,4*x] // BUG?

What is "poly1" -- is this a built-in marker to mark a vector as a polynomial vector? or is this something you created?
