\n" ); document.write( "\n" ); document.write( "TIME____________HEIGHT
\n" ); document.write( "Now (0)_________x
\n" ); document.write( "1_______________\"x%2B%280.1%29x=1.1x\"
\n" ); document.write( "2_______________
\n" ); document.write( "________________\"x%281%2B0.2%2B0.1%5E2%29=1.21x\"
\n" ); document.write( "3_______________\"1.21x%2B1.21x%280.1%29=1.21x%2B0.121x=highlight%281.331x%29\"\r
