To find: The equation of the ellipse with foci
Answer to Problem 52E
The equation of ellipse is
Explanation of Solution
Given information:
The foci of the ellipse are
Calculation:
The foci of ellipse lies on the x-axis. So, The major axis of the ellipse is horizontal.
So, the general equation of ellipse is
As the foci of the ellipse is
Therefore, the value of
Use the formula for eccentricity.
So, The value of
Use the formula.
Now substitute
Therefore, the equation of ellipse is
