True or False. All the occurrrences of the letter u in the title of this book are lower case. Justify your answer.

I said false, because they arn't being clear when they say "this" If even 1 book doesn't have a lowercase its false. But what is the method you would go about solving this?

I never took a negation of a non-if then statement. If its if then, its pretty easy:

~(Ax, if P(x) then Q(x)) equivlent too Ex such that P(x) and ~Q(x)

or

Ax in D, Q(x) equivlent Ex in D such that ~Q(x)

Note: A should be upside down, and E should be backwards.

THanks!
