--------------------------------------------
\n" ); document.write( "1.) Vertex at (2,5) Focus at (2,-3)\r
\n" ); document.write( "\n" ); document.write( "2.) Diretrix: x= 3/4 Focus: (5/9, -3)
\n" ); document.write( "--------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The directrix for your example (1) will be the line y=13.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can find the equations using these as guidance:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "derive parabola equation given known focus and directrix, vertex not at origin\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if vertex is at origin, derive equation for parabola given focus and directrix \n" ); document.write( "
