Distance calculation refers to the process of determining the space between two points. This can be done using various methods, such as the Euclidean distance, which measures the straight-line distance in a two-dimensional or three-dimensional space. Other methods include Manhattan distance, which calculates distance based on a grid-like path, and Haversine formula, used for measuring distances on the Earth's surface. In practical applications, distance calculation is essential in fields like geography, navigation, and computer science. For instance, GPS technology relies on accurate distance calculations to provide directions and locate positions. Understanding these calculations helps in optimizing routes and improving efficiency in travel and logistics.
