Show

  

show the current state of a problem or problems

 

Calling Sequence

Parameters

Description

Examples

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

with(Student[Calculus1]):

infolevel[Student[Calculus1]] := 1:

Rule[`+`](Diff(x^2+x, x));

Creating problem #1

ⅆⅆxx2+x=ⅆⅆxx2+ⅆⅆxx

(1)

Rule[`^`](Int(x^3, x));

Creating problem #2

x3ⅆx=x44

(2)

Show();

x3ⅆx=x44

(3)

Show(1);

ⅆⅆxx2+x=ⅆⅆxx2+ⅆⅆxx

(4)

ShowIncomplete(1);

?=ⅆⅆxx2

?=ⅆⅆxx

(5)

Show(%Diff3);

Problem 1:

ⅆⅆxx

(6)

Rule[`*`](Limit(x*exp(x), x=0, right));

Creating problem #3

limx0+xⅇx=limx0+xlimx0+ⅇx

(7)

Clear(1);

Problem #1 has been cleared

Show(all);

Problem 2:

Problem 3:

x3ⅆx=x44

limx0+xⅇx=limx0+xlimx0+ⅇx

(8)
