Variables Other than x in Formulas: PG Code Snippet
This code snippet shows the essential PG code to use variables other than x in formulas. 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 |
|---|---|
Context()->variables->add(t=>"Real");
$d = Compute("-16 t^2 + 5 t + 16");
|
We need make no changes to the documentation or initialization sections of the problem file. In the set-up section, we add the variable(s) (comma separated) that we need to the Context. If we want to exclude any existing variable(s), we can use |
BEGIN_TEXT
The height of an object thrown upwards with an
initial speed of 5ft/s from a height of 16ft is:
\{ans_rule(25)\}
END_TEXT
|
The text and answer sections of the file need not be changed. |
ANS( $d->cmp() ); |
