      sin(2x) + sin(x) = 0\r\n" );
document.write( "\r\n" );
document.write( "2sin(x)cos(x) + sin(x) = 0\r\n" );
document.write( "\r\n" );
document.write( "     sin(x)[2cos(x)+1] = 0\r\n" );
document.write( "\r\n" );
document.write( "  sin(x)=0;   2cos(x)+1 = 0\r\n" );
document.write( "  x=0; ;   2cos(x) = -1\r\n" );
document.write( "                 cos(x) = \r\n" );
