A = (1,2,3,4) B = (2,3,4,1)
A ^ B = (1,2,3,4) = A = B...
valid?
This is the one I am having the most trouble with, thanks in advance.
Determine, by any means, whether the following argument is valid or not:
"If a set A is a proper subset of another set B, then the intersection of A and B is also a proper subset of B; but A is equal to B or B is a proper subset of A; hence the intersection of A and B is a proper subset of A."
Before I try using LaTex to start the problem, is the file really a whole gig...heh.
In your example, this is true.but A is equal to B or B is a proper subset of A
And this is false in your example.hence the intersection of A and B is a proper subset of A
Then why not use { and } keys?My parentheses was meant to represent the squiggly lines, btw.
