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.
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.
