This PG code shows how to evaluate answers that are points or lists of points.
- File location in OPL: FortLewis/Authoring/Templates/Precalc/PointAnswers1.pg
- PGML location in OPL: FortLewis/Authoring/Templates/Precalc/PointAnswers1_PGML.pg
PG problem file | Explanation |
---|---|
Problem tagging: |
|
DOCUMENT(); loadMacros( 'PGstandard.pl', 'MathObjects.pl', 'contextLimitedPoint.pl', 'PGML.pl', 'PGcourse.pl' ); TEXT(beginproblem()); |
Initialization:
We only need to load |
Context('LimitedPoint'); $f = Compute('x^2-1'); $xint = List( Point('(1,0)'), Point('(-1,0)') ); $yint = List( Point('(0,-1)') ); |
Setup:
We could have used |
BEGIN_PGML Enter the [`x`]-intercept(s) and [`y`]-intercept(s) of [` y = [$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. + [`x`]-intercept(s): [_________________]{$xint} + [`y`]-intercept(s): [_________________]{$yint} [@ helpLink('points') @]* END_PGML |
Main Text: Be sure to tell students the proper syntax for how to enter their answers. |
BEGIN_PGML_SOLUTION Solution explanation goes here. END_PGML_SOLUTION ENDDOCUMENT(); |
