Explicație pas cu pas:
Se dau intervalele:
i1=[-5 ; 1/2]
i2=[1/2;3]
i3=[-2/4;2]
Calculati :
i1∩i3=[-5 ; 1/2]∩[-2/4;2]=[-5; 2]
i2\i3=[1/2;3] \[-2/4;2]=(2; 3]
i2∪i3=[1/2;3] ∪[-2/4;2]=[-1/2; 3]
i1∩i2∩i3=[-5 ; 1/2]∩[1/2;3]∩[-2/4;2]={1/2}
(i1\i2) ∪ (i3\i2)=( [-5 ; 1/2]\[1/2;3] ) ∪ ( [-2/4;2]\ [1/2;3] ) = [-5 ; 1/2) ∪ [-1/2; 1/2)=
= [-5 ; 1/2)
