Exercise 6| We introduce a language in which there are: - A constant me which represents the person who speaks, and a constant vegetables which represents the corresponding food; Two symbols of binary relations eat and likes: eat(p, a) represents the property "p eat a" and likes(p, a) the fact that "p likes a ". 1. Give the logical formulas that correspond to the following expressions: (a) I like everything I eat. (b) There are things that I do not like but that I eat anyway. (c) Those who do not like vegetables eat nothing. (d) If everyone agrees to eat something he does not like then I eat vegetables.
2. Use your own predicates P(x) and Q(x) to explain why (3r, P(x)) ^ (3x, Q(x)) is not logically equivalent to 3r, (P(x) A Q(x)).
