PG problem file | Explanation |
---|---|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "contextLimitedPoint.pl", ); TEXT(beginproblem()); |
Initialization:
We only need to load |
Context("LimitedPoint"); $f = Compute("x^2-1"); $xint = List( Point("(1,0)"), Point("(-1,0)") ); $yint = List( Point("(0,-1)") ); |
Setup:
We could have used |
Context()->texStrings; BEGIN_TEXT Enter the x-intercept(s) and y-intercept(s) of \( y = $f \). Enter a point as \( (a,b) \), including the parentheses. If there is more than one correct answer, enter a comma separated list of points. $BR $BR x-intercept(s): \{ ans_rule(20) \} \{ AnswerFormatHelp("points") \} $BR y-intercept(s): \{ ans_rule(20) \} \{ AnswerFormatHelp("points") \} END_TEXT Context()->normalStrings; |
Main Text: Be sure to tell students the proper syntax for how to enter their answers. |
$showPartialCorrectAnswers = 1; ANS( $xint->cmp() ); ANS( $yint->cmp() ); |
Answer Evaluation: |
Context()->texStrings; BEGIN_SOLUTION ${PAR}SOLUTION:${PAR} Solution explanation goes here. END_SOLUTION Context()->normalStrings; COMMENT('MathObject version.'); ENDDOCUMENT(); |
Solution: |
