Homework Statement
Given the ellipse is centered at the origin and the information, find an equation of the ellipse.
1) An ellipse with focus ([tex]\sqrt{5}[/tex],0), directrix; x = [tex]\frac{9}{\sqrt{5}}[/tex]
2) An ellipse with an eccentricity of 4/5
The Attempt at a Solution
I have to leave right now so I can't post a usuall good attept, but basically for #1) you cannot match the directrix with the a/e, but for #2) you are supposed to take the focus = 4
