endpoint
In mathematics, an endpoint refers to the starting or ending point of a line segment, ray, or interval
In mathematics, an endpoint refers to the starting or ending point of a line segment, ray, or interval. It represents the point at which the segment or interval begins or terminates.
For example, consider a line segment AB. The endpoints are denoted by A and B. A is the starting point of the line segment, and B is the ending point.
When representing an interval, we use brackets to indicate a closed interval, where the endpoints are included (e.g., [a, b]). On the other hand, parentheses are used to indicate an open interval, where the endpoints are not included (e.g., (a, b)).
Understanding endpoints is essential when working with geometric shapes, graphing functions, or solving equations involving intervals. It allows us to identify the specific points where a segment begins or ends, helping us analyze and solve mathematical problems accurately.
