Hi everybosy!

I tried to use "nabla" and parcial derivations keyboard symbols to define a function that calculates a function nabla, divergence, etc, but encounter that this symbols are reserved.

?Does exist some way to use that symbols? ?Does exist some application to solve Vectorial Calculus?

I appreciate some help

Regards

Carlos Villase?or

para derivadas parciales usa el comando diff(, actua igual porque el te pide la variable con respecto a la que quieres derivar y toma constante el resto. teclea la expresion seleccionala, y luego interactivo/diff. llena el cuadro de dialogo y listo

Para rotacionales y divergencias podrias crear un programa que pida la ecuacion y retorne el resultado, usaras el comando diff tambien.

vere si puedo hacerlo y subirlo al file sharing

This is just a derivation problem, if I understood, he didn't know how to derivate a function.

i think he wants to use \nabla as a function name ans define a "gradient" function, but the symbol is reserved and not allowed in fun names

we can only define 'grad', 'div', 'rot', ... functions (using diff function), we can't name it \nabla
