Formula of Vertices of an Ellipse Calculator
To understand how the calculator works, it’s essential to familiarize yourself with the basic concepts and formulas related to an ellipse:
Standard Ellipse Equation:
Finding Vertex Coordinates:
The vertices of an ellipse are pivotal points located along its major axis. The major axis is the longest diameter of the ellipse, and the distance between a vertex and the ellipse’s center is known as the major radius (a). To find the coordinates of the vertices, one must understand the following:
- The vertices lie on the major axis (axis with the larger radius, a).
- The distance between a vertex and the center (c₁, c₂) is equal to the major radius (a).
Consequently, the formula to calculate the vertex coordinates is as follows:
(c₁ + a, c₂) (vertex to the right of the center)
(c₁ – a, c₂) (vertex to the left of the center)
Example:
Consider an ellipse with the equation: (x - 2)² / 4² + (y - 3)² / 1² = 1.
Here:
- Center: (c₁, c₂) = (2, 3)
- Major radius (a) = 4 (since 4 is bigger than 1)
Thus, the vertex coordinates are:
- (2 + 4, 3) = (6, 3) (vertex to the right)
- (2 – 4, 3) = (-2, 3) (vertex to the left)
