ShowSteps

  

show the steps taken toward the solution of a problem or problems

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

ShowSteps(expr, showrules=tf)

Parameters

expr

-

(optional) algebraic, algebraic equation, or all; select the problem(s) to show

tf

-

(optional) truefalse; indicates whether or not to display the rules applied together with the results (default: true)

Description

• 

The ShowSteps command displays the sequence of steps of the problem from its initial state to its current state.  The display is accomplished using calls to print; the value returned by ShowSteps is NULL.  Thus, the history variables, %, %%, and %%%, are not modified by this command.

• 

This command can be applied interactively by using the DiffTutor, IntTutor, or LimitTutor.

• 

If called with no arguments, 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 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.

• 

The showrules option specifies whether or not to display the rules which have been applied at each step.

• 

Unlike for the Show and ShowIncomplete commands, a subproblem label is not valid input to this command.

• 

Maple returns an error if you attempt to display a problem that has been cleared by a call to the package routine Clear.

• 

This command does not change which problem is designated the current problem.
