| PG problem file | Explanation |
|---|---|
|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "parserDifferenceQuotient.pl", ); TEXT(beginproblem()); |
Initialization:
We need to include the macros file |
Context("Numeric");
$limit = DifferenceQuotient("2*x+h","h");
$fp = Compute("2 x");
|
Setup:
The routine |
Context()->texStrings;
BEGIN_TEXT
Simplify and then evaluate the limit.

$BR
\( \displaystyle
\frac{d}{dx} \big( x^2 \big)
=
\lim_{h \to 0} \frac{(x+h)^2-x^2}{h}
=
\lim_{h \to 0}
\big(
