Where are the foci and major axis located in an ellipse?
Where are the foci and major axis located in an ellipse?
- Foci are on the top and bottom, major axis is at the narrowest point
- Foci are both on the left side, major axis at the widest point
- Foci are to the left and right, major axis is through the center at the widest point (correct)
- Foci are on the edges, major axis is at the center
How do you calculate eccentricity for an ellipse?
How do you calculate eccentricity for an ellipse?
- Eccentricity = major axis length / focal distance
- Eccentricity = focal distance / major axis length (correct)
- Eccentricity = focal distance / minor axis length
