zatvoreni interval realnih brojeva
Skraćeni oblik: zatvoreni interval
Definicija: interval koji sadržava krajnje elemente
Napomena: Kada se kaže samo "zatvoreni interval", u pravilu se misli na zatvoreni interval u skupu realnih brojeva, iako je uporaba naziva puno šira.
Dopušteni nazivi: segment
Simbol: \([a,b]\)
Engleske istovrijednice: closed interval, segment

Cilj projekta "Hrvatsko nazivlje u matematici" je na jednom mjestu prikupiti i obraditi sve hrvatske nazive koji na izravan ili neizravan način imaju veze s matematikom. Ako želite na bilo koji način doprinijeti ostvarenju ciljeva ovog projekta, molim javite se voditelju projekta na adresu goran.igaly@math.hr
WMW naziv: closed interval
WMW klasifikacija: Geometry > Line Geometry > Ranges >
WMW definicija: An interval is a connected portion of the real line. If the endpoints \(a\) and \(b\) are finite and are included, the interval is called closed and is denoted \([a,b]\). If the endpoints are not included, the interval is called open and denoted \((a,b)\). If one endpoint is included but not the other, the interval is denoted \([a,b)\) or \((a,b]\) and is called a half-closed (or half-open interval).
WMW napomena: If one of the endpoints is \(\pm \infty\), then the interval still contains all of its limit points, so \([a,\infty)\) and \((-\infty,b]\) are also closed intervals. Intervals involving infinity are also called rays or half-lines. If the finite point is included, it is a closed half-line or closed ray. If the finite point is not included, it is an open half-line or open ray.
