\n" ); document.write( "1. circle with center at (3,-1) and radius is 4 \"%28x-3%29%5E2+%2B+%28y%2B1%29%5E2+=+4%5E2+\"
\n" ); document.write( "2. Ellipse with vertex at(0,12) and co-vertices at(-8,0), C(0,0) \"%28x%29%5E2%2F12%5E2+%2B+%28y%29%5E2%2F8%5E2+=+1+\"
\n" ); document.write( "3. Hyperbola with vertex at (0,4),focus at(0,5) and center at(0,1)
\n" ); document.write( "\"%28y-1%29%5E2%2F3%5E2+-+%28x%29%5E2%2F7+=+1\" 4 = sqrt(3^2 + 7 )
