One of my problems has two cases depending on the sign of the randomized variable x. I have written out complete solutions for each of the two cases. Question: How can I display only the solution for relevent case? I tried the
obvious "if" statement but it didn't work.
For the record here's my code for solutions, based on http://webwork.maa.org/wiki/PopUpLists :
#Context()->texStrings;
SOLUTION(EV3(<<'END_SOLUTION'));
$PAR SOLUTION $PAR
Solution:
(solution goes here)
END_SOLUTION
#Context()->normalStrings;
--------------
On a related note, how can I use tex mode in solutions? Webwork displays \( x \) as plain text...
Thanks!
I found the answer: The standard if/then/else loop works if you put it outside the SOLUTION/END_SOLUTION environment:
if($m % 2 == 0){ SOLUTION(EV3(<<'END_SOLUTION')); $PAR SOLUTION $PAR \( $m \) is even END_SOLUTION } else{ SOLUTION(EV3(<<'END_SOLUTION')); $PAR SOLUTION $PAR \( $m \) is odd END_SOLUTION } #Context()->normalStrings; a,b,c are integers for the following snippet.
@EO = ( 'Even' , 'Odd' ) ;
$ap = @EO[ $a % 2 ] ;
$cp = ($c % 2 == 0) ? 'Even' : 'Odd' ;
Context()->texStrings;
BEGIN_SOLUTION
$SOLUTION
\( $a \) is $ap,
$b is @EO[$b % 2],
\( $c \) is $cp
END_SOLUTION
Context()->normalStrings;
Note: neither "Context()" command is commented-out, the new BEGIN_SOLUTION is used to initiate the block, and $SOLUTION to display bolded "Solution:".
