    Ellipse- Clarification.

    When working with ellipse,

    it must be :

    (x-h)^2/(a^2) + (y-k)^2/(b^2) = 1

    or (y-k)^2/(a^2) + (x-h)^2/(b^2)=1

    c^2= a^2- b^2

    (a>b)

    a determines the major axis correct? So if a^2 is always under (x-h)^2 then the major axis is going to run along the x-axis, and if a^2 is under (y-k)^2, then the major axis is going to run along the y-axis.


    Can anyone confirm if all of this info is correct, reflecting on ellipse graph. Also, ellipses cannot have a negative denominator right? and Extrancitiy is c/a, and C are the foci along the major axis.

    Thank you,
