Homework Statement


I have two sets E and L.
I have to show that E is a subset of L, using only complement, union and the empty set.
I.e. all members of E also have to be members or L, but L may contain members not included in E.


Homework Equations





The Attempt at a Solution


Am I right in describing it thus:
complement(complement(E) union L) = Ø

Any help is appreciated.

Sincerely,
tsrgb
