Hi there,
\n" ); document.write( "1) F = kd
\n" ); document.write( "2) C = kw
\n" ); document.write( "3) S = kd
\n" ); document.write( "4) r = k/t
\n" ); document.write( "5) c = k/n
\n" ); document.write( "Incidentally, if you have a combination
\n" ); document.write( "for example:
\n" ); document.write( "D varies directly as P and inversely as Y
\n" ); document.write( "This would be:-
\n" ); document.write( "D = kP/Y
\n" ); document.write( "(k is always on the top line)
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
