Use of Canvas Elements in Maple Library Commands 

In this page we will highlight a few of the commands that generate a Canvas suitable for use in both Maple and Maple Learn.  

SolvePractice 

The SolvePractice command generates a canvas with SolveFeedback as the command behind the button.  

 

>	with(Grading):

 

>	SolvePractice(2*x + 3 = 4*x - 5, x);

 

 

The canvas structure can be extracted directly by using the 'output'='canvas' option.   

>	cv := SolvePractice(2*x + 3 = 4*x - 5, x, 'output' = 'canvas'):

 

>	DocumentTools:-Canvas:-ShowCanvas(cv);

 

You can also specify 'output'='link' to create a shared Maple Learn Document. 

>	SolvePractice(2*x + 3 = 4*x - 5, x, 'output' = 'link'):

PracticeSheet 

The PracticeSheet command allows for automatic pattern-based generation of many problems on a single sheet.  
 

>	with(Student:-Basics):

 

>	cv := Student:-Basics:-PracticeSheet("integer/integer(range=2..5)+integer/integer(range=2..5)", title = "Addition of Fractions", message = "Add and reduce each expression", output = canvas):

 

>	with(DocumentTools:-Canvas):

 

>	ShowCanvas(cv, entrybox = false);

 

ShareCanvas(cv);

Steps 

Maple has many algorithms for showing step-by-step methods explaining how to simplify, solve, integrate, etc.  These solution steps can be generated as a canvas. 

 

>	Student:-LinearAlgebra:-DeterminantSteps( <1,2,4; 3, 4, 5; 5,6,7> );

 

(3.1)

 

>	Student:-LinearAlgebra:-DeterminantSteps( <1,2,4; 3, 4, 5; 5,6,7>, 'output'='link' );

Create Your Own Steps Output  

All of the Steps routines generate a series of records with math and annotations, and possibly one level of sub-steps.  These are processed by the OutputStepsRecord command.  Here is an example of a record with math, annotations, and substeps:
 

>

steps := [  Record(math=<2*x+5*y=19,x-2*y=-4>,annotation="solve system"),  Record(math=(x=2*y-4),annotation="solve equation 2 for x",         substeps=[             Record(math=(x-2*y=-4),annotation="equation 2"),             Record(math=(x=-4+2*y),annotation=_MTEXT("add %1 to both sides",2*y))         ]  ),  Record(math=(y=3),annotation="substitute value of x into equation 1 and solve",         substeps=[             Record(math=(2*x+5*y=19),annotation="equation 1"),             Record(math=(2 %* (2*y-4)+5*y=19),annotation="sub in value for x"),             Record(math=(4 %* y-8+5 %* y=19),annotation="expand"),             Record(math=(9*y-8=19),annotation="collect"),             Record(math=(9*y=27),annotation="add 8 to both sides"),             Record(math=(y=3),annotation="divide both sides by 9")         ]  ),  Record(math=(x=2 %* (3)-4),annotation=_MTEXT("substitute %1 into %2",y=3,x=2*y-4)),  Record(math=(x=2),annotation="simplify"),  Record(math=<x=2,y=3>,annotation="solution") ]:

 

>	Student:-Basics:-OutputStepsRecord(steps);

 

>	cv := Student:-Basics:-OutputStepsRecord(steps,output=canvas):

 

>	DocumentTools:-Canvas:-ShareCanvas(cv);

 

The OutputStepsRecord command allows for different 'displaystyle' options.
 

>	rec := Student:-Calculus1:-ShowSolution( Int(  x*sin(x), x ), output=record ):

 

>	Student:-Basics:-OutputStepsRecord( rec, displaystyle=columns );

 

 

 

This example generates a link to Maple Learn with animated steps: 

>	Student:-Basics:-OutputStepsRecord( rec, displaystyle=columns, animated=true, output=link );

Quiz 

The Quiz command lets you create a variety of question types with options for custom grading procedures, feedback, and try-another generation.  Here are some samples: 

True or False 

>	with(Grading): with(DocumentTools:-Canvas):

 

>	cv := Quiz("Is 1 + 1 = 2? ", true, 'style' = truefalse, output=canvas):

 

>	ShowCanvas(cv, entrybox=false);

 

 

>	ShareCanvas(cv);

Multiple Choice and Multiple Select 

>	cv := Quiz("Which of the following could be portions of the plot of sin(x)?", {1, 2}, [plot(sin(x), x = 0 .. rand(2 .. 3)()), plot(sin(x), x = rand(2 .. 3)() .. 5), plot(2*sin(x), x = rand(2 .. 3)() .. rand(4 .. 7)())], style = multipleselect, gradebyindex = true, size = [250, 150], output=canvas):

 

>	ShowCanvas(cv, entrybox=false);

 

ShareCanvas(cv);

>	ShowCanvas(cv,'entrybox'=false);
