format and/or display annotated steps
list of records
(optional) columns, compact, or linear
(optional) print, printf, typeset, canvas, script, list, record, link
The OutputStepsRecord command is used to format and display a "steps" data structure, used by many of the internal Student commands for showing the steps of solving a math problem. Such a command creates a list of Records containing "math" and "annotation"s, and this routine takes care of displaying those steps in a consistent way.
The displaystyle option controls the layout of the content.
When displaystyle=columns, substeps are split out into a second column to the right of the main steps.
When displaystyle=linear, annotations appear on their own line as a title, preceding the math for each step.
When displaystyle=compact, annotations appear on the same line, to the right of the math, except for annotations that introduce a series of substeps, which appear on their own line as a title.
The output option controls the rendering mechanism and return value.
output=typeset is the default rendering mode when using the Standard Worksheet Interface. It displays textbook style math in a layout according to displaystyle.
output=printf is the default rendering mode when using the Command-line version of Maple. It displays ASCII style math notation, and is ideal for copy & paste into an email or text-based application.
output=print uses the print command to render output in a linear centered fashion.
output=canvas returns a XML string that can be used as part of a MapleLearn document.
output=link deploys the steps as a MapleLearn document and provides a web hyperlink to the document as output.
output=script returns a DocumentTools:-Canvas:-Script object.
output=record returns the input as a Record
output=list returns the input as a list of lists
This function is part of the Student[Basics] package, so it can be used in the short form OutputStepsRecord(..) only after executing the command with(Student[Basics]). However, it can always be accessed through the long form of the command by using Student[Basics][OutputStepsRecord](..).

• solve system
Matrix(2, 1, [[2*x+5*y = 19],[-2*y+x = -4]])
▫ solve equation 2 for x
◦ equation 2
-2*y+x = -4
◦ add 2*y to both sides
x = 2*y-4
▫ substitute value of x into equation 1 and solve
◦ equation 1
2*x+5*y = 19
◦ sub in value for x
2*(2*y-4)+5*y = 19
4*y+5*y-8 = 19
9*y-8 = 19
◦ add 8 to both sides
9*y = 27
◦ divide both sides by 9
y = 3
• substitute y = 3 into x = 2*y-4
x = 2*3-4
x = 2
Matrix(2, 1, [[x = 2],[y = 3]])
solve equation 2 for x
add 2*y to both sides
substitute value of x into equation 1 and solve
sub in value for x
add 8 to both sides
divide both sides by 9
substitute y = 3 into x = 2*y-4
