**Calculation Details:**

**Formula used:** Distance = √((X2 - X1)^2 + (Y2 - Y1)^2)

**Explanation:** The formula calculates the Euclidean distance between two points in a 2D plane. It measures the straight-line distance between Point 1 (X1, Y1) and Point 2 (X2, Y2).

**Detailed Calculation:** The calculation involves finding the difference in X and Y coordinates, squaring them, summing the squares, and taking the square root of the sum to get the distance.

**Calculation History:**

## What is 2D Distance?

The 2D distance, also known as the Euclidean distance, between two points (x1, y1) and (x2, y2) in a two-dimensional plane can be calculated using the following formula:

Distance = √((x2 – x1)^2 + (y2 – y1)^2)

Here:

- (x1, y1) are the coordinates of the first point.
- (x2, y2) are the coordinates of the second point.
- √ denotes the square root operation.
- (x2 – x1)^2 represents the squared difference of the x-coordinates.
- (y2 – y1)^2 represents the squared difference of the y-coordinates.

## All Formulae Related to 2D Distance

- Euclidean Distance:
- Formula: √((x2 – x1)^2 + (y2 – y1)^2)
- Calculates the straight-line distance between two points in a 2D plane.

- Manhattan Distance:
- Formula: |x2 – x1| + |y2 – y1|
- Calculates the distance between two points in a grid-like fashion, where you can only move horizontally or vertically (no diagonal movement).

- Minkowski Distance:
- Formula: [Σ(|xi – yi|^p)]^(1/p) for i = 1 to n (for n-dimensional space)
- Generalizes distance calculation by introducing a parameter ‘p’. When p=1, it’s the Manhattan distance; when p=2, it’s the Euclidean distance.

- Chebyshev Distance (Chessboard Distance):
- Formula: max(|x2 – x1|, |y2 – y1|)
- Measures the distance when movement is allowed in all directions (horizontal, vertical, diagonal).

- Hamming Distance (for binary vectors):
- Formula: Σ(|xi – yi|) for i = 1 to n
- Measures the difference between two binary vectors of equal length.

- Cosine Distance (for vectors):
- Formula: 1 – (Σ(xi * yi) / (sqrt(Σ(xi^2)) * sqrt(Σ(yi^2))))
- Measures the cosine of the angle between two vectors, used in vector space similarity analysis.

- Jaccard Distance (for sets):
- Formula: 1 – (|A ∩ B| / |A ∪ B|)
- Measures the dissimilarity between two sets by comparing their intersection and union.
