How do you find the a, b, c for #(x + 3)^2/9 + (y – 9)^2/25 =1#?
Find them by a bit of rewriting of the equation and using the formula that
First, rewrite the equation of this ellipse in the form
Therefore, the distance between the center of the ellipse and the two foci is
FYI, the center of the ellipse is the point whose rectangular coordinates are
