Web29 May 2024 · To distinguish between open and closed intervals. An open interval (a, b) and a closed interval [a, b] differ in that at the open interval (a, b) the edge points a and b are not elements of the interval, while this is the case with the closed interval [a, b] is already the case. This is also the main difference between the two types of intervals, which explains … WebIn interval notation, we use a square bracket [ when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded.
