\n" ); document.write( "What is the minimum period required for the exercise before a festive season?
\n" ); document.write( "----------
\n" ); document.write( "Comment: If you let d(w)=2000 and then solve for w you
\n" ); document.write( "will get a negative value for w. Something is wrong
\n" ); document.write( "with the formula.
