Simplify the following\r
\n" ); document.write( "\n" ); document.write( "\"Sin%5E2%28x%29%2F%281%2Bcos%28x%29%29+-1\"
\n" ); document.write( " = \"%281+-+cos%5E2%28x%29%29%2F%281%2BCos%28x%29%29+-1\"
\n" ); document.write( " = \"%281+-+cos%28x%29%29+-1\"
\n" ); document.write( "= -cos(x)
\n" ); document.write( "
\n" );
