Find the co-ordinates of the centre and foci of the ellipse with equation
What are the coordinated of its verices and the eqns of the directrices?
I've managed to manipulate the eqn to this form
Therefore got the centre as (2,8).
I did vertex, directrix and foci for parabolas but not for an ellipse what are the formula? :s i've tried looking them up on the web but it's all confusing. So far i think
Can someone help me out with just this one ? >.< got a whole load more of em to work through that are similar just im stuck at the first hurdle haha
Have a look here: Ellipse -- from Wolfram MathWorld
