1, this formula can be used to calculate the straight line distance between two points. If two points P 1 and P2 are on the same straight line, then the distance between them is the length of the straight line between them. In engineering, this formula can be used to calculate the distance between two points to determine the position relationship and motion trajectory between objects.
2. The distance formula between two points can also be used to calculate the oblique distance between two points. If two points P 1 and P2 are not on a straight line, then the oblique distance between them is the square root of the straight line distance between them.
3. In practical application, the distance formula between two points can be used to solve many problems. For example, in geography, the distance between two points can be calculated by this formula, and the distance and direction between two points can be determined by this formula. In physics, this formula can be used to calculate the distance between two points to determine the interaction and motion law between objects.
