distance in math definition. Suppose youre given the two points 2 1 and 1 5 and they want you to find out how far apart they are. In physics or everyday discussion distance may refer to a physical length or an estimation based on other criteria.
A linear extent of space. The distance between two points is the length of a straight line segment that links them. Unusual definitions of distance can be helpful to model certain physical situations but are also used in theoretical mathematics.
Manhattan distance is a rectilinear distance named after the number of blocks in the north south east or west directions a taxicab must travel on in order to reach its destination on the grid of streets in.
The line extending from the center of a sphere to any point on the outside edge of the sphere. This lesson describes the mathematical formula for determining distance and gives some examples. In mathematics the Euclidean distance or Euclidean metric is the ordinary distance between two points that one would measure with a ruler and is given by the Pythagorean formula. A topological space whose topology can be described by a metric is called metrizable.
