 Show - Maple Help

Student[Calculus1]

 Show
 show the current state of a problem or problems Calling Sequence Show(expr) Parameters

 expr - (optional) algebraic, algebraic equation, or all; specify the problem(s) Description

 • The Show command displays the current state of a single problem or all problems from the current Maple session.  The display is accomplished using calls to print; the value returned by Show is NULL.  Thus, the history variables, %, %%, and %%%, are not modified by this command.
 • If called with no arguments, the problem  designated the current problem is displayed. To designate a problem the current problem, create a new problem (see Rule or Hint) or use the GetProblem command.
 • If expr is a positive integer, the corresponding problem is displayed.
 • If expr is a subproblem label (see ShowIncomplete), the current state of the corresponding subproblem is displayed.  This subproblem need not be a subproblem of the current problem.
 Note: Treat subproblem labels as temporary objects because the application of a rule to a problem can change the underlying problem representation, and hence the subproblem labels.  It is recommended that you call ShowIncomplete to verify the value of a label before passing it to Show.
 • If expr is the keyword all, the current states of all problems from the current session are displayed.  Note: Problems that have been cleared by a call to Clear are not displayed.
 • If expr is the output from a previous call to Rule or GetProblem (with the internal option), or the left-hand side of such output, the current state of that problem is displayed.
 • This command does not change which problem is designated the current problem. Examples
