Určení průniků intervalů
Urči průnik intervalů A=(-2 ; 2\rangle a B=\langle 0 ; 4).
K=A \cap B=(-2 ; 2\rangle \cap\langle 0 ; 4)=\langle 2 ; 4)
K=A \cap B=(-2 ; 2\rangle \cap\langle 0 ; 4)=(-2 ; 4)
K=A \cap B=(-2 ; 2\rangle \cap\langle 0 ; 4)=\langle 0 ; 2\rangle
K=A \cap B=(-2 ; 2\rangle \cap\langle 0 ; 4)=(-2 ; 0\rangle
Uděláš tedy průnik dvou intervalů A a B a získáš tak nový interval, který bude obsahovat čísla, která jsou jak v intervalu A, tak zároveň i v intervalu B.
