Re: HP-Prime Polynomials: User Guide and Request Message #3 Posted by CompSystems on 27 Sept 2013, 11:34 p.m., in response to message #2 by Michael Lopez 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
