document.write( "x = 3 cos t, \r\n" );
document.write( "\r\n" );
document.write( "y = 3 sin t\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Square both equations and then add them. You will get\r\n" );

document.write( "\r\n" );
document.write( " +  =  +  =  = 9.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus finally your equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( " = 9.     (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is the equation of the circle of the radius 3 units centered at the origin of the coordinate system at (x,y)-coordinate plane.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus the parameter  \" t \"  is just eliminated, and the result is the equation (1).\r\n" );
