The convert(procedure, algebraic) command converts a given procedure into its algebraic form, if possible. For example, the procedure z -> sin(z) + 1 is converted into sin + 1. Remember that in Maple 1(z) = 1.

When the conversion to the algebraic form is not possible, the received procedure itself is returned. For a conversion to be possible, the given procedure is expected to have a calling sequence, that is, be a procedure of some arguments, and return an algebraic expression of its arguments containing only constants or functions of the given arguments.
