For logic Taking the universe of discourse to be the set {1, 2, 3}, specify extensions for “F”, “G”, and “H” that make the following schemata true: (a) (∃x)(Fx≡Gx) • ~(∀x) (Fx ⊃ Gx) • (∀x)(Gx ⊃ Fx) (b) (∀x)(Fx • Gx ⊃ Hx) • (∀x)(Fx ⊃ Gx • Hx) • (∀x) (Gx ⊃ Fx • Hx)

4. Suppose that the variable x represents people, and F(x): "x is friendly" T(x): "x is tall" A(x): "x is angry".

4. Translate the following sentences from English to predicate logic. The domain that you are working over is X, the set of people. You may use the functions S(x), meaning that " x has been a student of 6.042," A(x) meaning that "x has gotten an 'A' in 6.042," T(x) meaning that "x is a TA of 6.042," and E (x, y) meaning that "x and y are the same person." (i) There are people who have taken 6.042 and have gotten A's in 6.042. (ii) All people who are 6.042 TA's and have taken 6.042 got A's in 6.042. (iii)There are no people who are 6.042 TA's who did not get A's in 6.042.

Let F(x,y): "x is friend with y", N(x): "x is funny", W(x): "x is wise", R(x): "x is fair". The domain for x and y is the set of all persons. Write the negation in English starting by "Some .. " of: Ey w(x)→R(y) A F(x,y)
why don't we use the existential instantiation(∃x) instead of the universal because it says "A car" which means there exists one in the domain.

a. Construct an interpretation (i.e., give the domain and the meaning of P(x)) in which (∀x)P(x) has the value true.b. Construct an interpretation in which (∀x)P(x) has the value false.c. Can you find one interpretation in which both (∀x)P(x) is true and (∃x)P(x) is false?d. Can you find one interpretation in which both (∀x)P(x) is false and (∃x)P(x) is true?
