(a)
Answer to Problem 5CFU
An ellipse
Explanation of Solution
Given information:
Calculation:
As the eccentricity is between 0
This indicates an ellipse.
(b)
To identify: Conic section given its eccentricity
(b)
Answer to Problem 5CFU
A parabola
Explanation of Solution
Given information:
Calculation:
On a parabola, e will always be 1 because the distance from the directix to a point, will always be the same as the distance from the point to the focus.
(c)
To identify: Conic section given its eccentricity
(c)
Answer to Problem 5CFU
A hyperbola
Explanation of Solution
Given information:
Calculation:
A hyperbola will always have a value for e greater than 1 because the distance from the directrix to a point on the graph is always more than the distance from the point to the focus.
(d)
To identify: Conic section given its eccentricity
(d)
Answer to Problem 5CFU
A circle
Explanation of Solution
Given information:
Calculation:
Because on a circle, the foci are at the center, c = 0.
Since
This will always produce an
