Description
Similar to the
Formula type. Answers may be any kind of
formula, entered in calculator syntax, but responses are
graded as correct if they differ from the given answer by a
constant value. Answers may include variables and standard
functions. This question type is intended for use in
questions asking the student to evaluate indefinite
integrals.
Notes
- The
\answer
field must be in calculator
syntax, not in TeX. Enter the answer as
you would expect the student to enter it (although
equivalent answers will be graded correctly). Do not
include "+ C
" in the answer.
Examples
\begin{question}{Formula Mod C}
\qutext{Calculate $\int 6x^2\, dx$.}
% Use calculator syntax for the answer, NOT TeX:
\answer{2x^3}
% Note that the response '2x^3+1' would also be graded as correct.
\end{question}
\begin{question}{Formula Mod C}
% This question uses algorithmic variables.
\qutext{Calculate $\int \var{2*\var{a}}x+\var{b}\, dx$.}
\answer{\var{a1}x^2+\var{b}x}
\code{$a = range(2,10);
$a1 = int(switch(rint(2),$a,-$a));
$b = range(1,20);}
\end{question}
