Conic Sections: Ellipses

(X^2/a^2)+(y^2/b^2)=1or(x^2/b^2)+(y^2/a^2)=1-a^2 is always the largest #-the axis divided by a^2 is the axis the elipse is grapghed on-to find foci use the formula b^2=a^2-c^2-to find the focal endpoints use the formula b^2/a, it is the distance between the focus and the endpoint-canter of graph will be at (0,0)
