Formatting Correct Answers: Equations: PG Code Snippet
This code snippet shows the essential PG code to check student answers that are equations. Note that these are insertions, not a complete PG file. This code will have to be incorporated into the problem file on which you are working.
| PG problem file | Explanation |
|---|---|
loadMacros("parserImplicitPlane.pl");
|
We don't have to change the tagging and documentation section of the problem file.
In the initialization section, we need to include the macros file |
$dfx = 3;
$yintercept = 4;
Context("ImplicitPlane");
Context()->variables->remove("z");
$h = ImplicitPlane("y = $dfx x + $yintercept");
|
In the problem set-up section of the file, we specify that the Context should be Notes: on using this and related Contexts. |
BEGIN_TEXT ...... question text ...... END_TEXT |
The problem text section of the file is as we'd expect. |
ANS( $expr->cmp() ); |
As is the answer. |
