Math Problem Statement
V(-2,2) and (-2,8) and length of minor axis is 6
Solution
You're describing an ellipse, where the two points are likely the vertices along either the major or minor axis, and the length of the minor axis is provided as 6.
Let's break down the problem step by step:
-
Vertices: You provided two points, and . These points have the same -coordinate, meaning they lie vertically along the y-axis. This suggests that these are the endpoints of the major axis (because the major axis is usually longer than the minor axis, and the points are further apart vertically).
-
Length of Major Axis: The distance between these two points can be calculated as the difference in the -coordinates, which is: So, the length of the major axis is 6.
-
Center of the Ellipse: The center is located at the midpoint of the major axis. The midpoint between and is: So, the center of the ellipse is at .
-
Length of Minor Axis: It's given that the length of the minor axis is 6.
Equation of the Ellipse
The standard form for the equation of an ellipse centered at is: where:
- is the center,
- is half the length of the major axis,
- is half the length of the minor axis.
In this case:
- The center is ,
- The length of the major axis is 6, so ,
- The length of the minor axis is 6, so .
Thus, the equation of the ellipse is: or simplified:
This is the equation of the ellipse.
