Find the center, vertices, foci and eccentricity of the ellipse and sketch the ellipse
Answer to Problem 37E
Center:
Vertices:
Foci:
Eccentricity:
Given:
The given equation is
Explanation:
The given equation represents an ellipse with major axis horizontal.
The standard equation of an ellipse with major axis horizontal is given by
Comparing this with equation (1),
Thus, the center of the ellipse is
Now, since the vertices are at
Next,
Thus,
The foci lie on the points
The foci are at
The eccentricity of the ellipse is given by
Thus,
The graph of the given ellipse is depicted below:
