Answer:
The standard form of the ellipse is . Coordinates of the foci are and , respectively.
Step-by-step explanation:
The equation of a ellipse centered in the origin in standard form is defined by following formula:
(1)
Where are the coefficients of the ellipse.
Now we proceed to transform the equation of the ellipse in general form into standard form by algebraic means:
Since , then major axis of the ellipse is located in y-axis. The distance between center and focus () is calculated by following Pythagorean identity:
(2)
The location of the foci are represented by and . If we know that , then the location of the foci are, respectively:
,
