1.write an equation in standard form for the ellipse shown with center (0,0) , focus (0,6) co-vertex(0,-10).Given ellipse has a vertical major axis. (Note: focus and co-vertices cannot both be on the vertical major axis. I will assume you meant the co-vertex coordinates given are instead those of the vertex.)\r

\n" ); document.write( "center:(0,0)
