Closed-Form Expression

  1. Jul 19, 2009 #1

    I have a mathematical expression that consists of a limited number of derivatives of some functions, and these derivatives exist and well defined. Can we call this expression a closed-form expression?

    Probably not.
    Unless there is given a special definition of "closed form" .

    The problem is: there is no agreement about the exact definition of the well known functions in the definition of the closed-form expression. I have special functions whose derivative remains the same but with different parameters. I don't know, is this closed form? I have to know to write it down in my thesis.
