## Formula

To calculate the center of an ellipse, we use the following formula:

```
(x-h)²/a² + (y-k)²/b² = 1
```

where `(h, k)`

is the center of the ellipse.

## Categories of Center of Ellipse Calculations

Category | Range |
---|---|

Small ellipse | (h, k) within 5 units |

Medium ellipse | (h, k) within 5-15 units |

Large ellipse | (h, k) greater than 15 units |

## Examples

Individual | Ellipse Dimensions | Center Calculation |
---|---|---|

Pirate Pete | 8×6 | (4, 3) |

Astronaut Amy | 12×10 | (6, 5) |

Mathematician Max | 16×12 | (8, 6) |

## Calculation Methods

Method | Advantages | Disadvantages | Accuracy |
---|---|---|---|

Algebraic | Simple | Not always accurate | Moderate |

Geometric | Visual | Requires drawing | High |

## Evolution of Concept
