Q4. Simplify the following sentences in predicate logic so that all the negation symbols are directly in front of a predicate. (For example, Vr (-0(1)) (-E(r))) is simplified, because the negation symbols are directly in front of the predicates O and E. However, Vr -(P(x) V E(x)) is not simplified.) (i) -(3r (P(x) V (E(x) → S(x)))) (ii) -(Vz (E(r) A (P(x) →¬(3y G(x, y))) Q5. Write a sentence in predicate logic (using the same predicates as above) which is true when the domain is the class of positive integers (1, 2, 3, ...), but is false when the domain is the class of all integers (...,-2, -1,0, 1, 2, ...). (You do not need to explain your answer.)

6) In the domain of all computer science majors, let G(x) be the predicate "x is required to take geometry". Write the following statements in the symbols of predicate logic. a) There is a computer science major that is not required to take geometry. b) There is no computer science major that is required to take geometry. c) Every computer major is not required to take geometry. d) All computer science majors are required to take geometry.
4d. In the following exercises I give you the symbols that you will use for predicates or relations. Your task is to paraphrase the English sentences in quantified relational logic. For example, suppose you have the English sentence “Something is missing” (M, missing), then the paraphrase is ∃xMx. (iv) Only white swans exist. (S, swan; W, white) (v) A swan is white. (S, swan; W, white) (The image is just formuals if your not familiar with this)

Jane made this statement about Ahmad, another student in her class. If Ahmad passes the final exam, then Ahmad will get an A in the class. (a) Statements p and q are defined as follows. p: Ahmad passes the final exam. q: Ahmad gets an A in the class. Write Jane's statement in symbolic form using p and q. (b) Suppose the following situation occurred. Ahmad didn't pass the final exam. On his report card, Ahmad in the class. Complete the table to determine the truth of Jane's statement in this situation.
Let D(z) be "z is a day", S(r) be "r is sunny", R(r) be "x is rainy", M be "Monday", and I be "Tuesday". Using these predicate symbols and appropriate quantifiers, write each English language statement as a predicate wff. Note: The domain is the whole world. (a) Some days are sunny and rainy. (b) No day is both sunny and rainy. (c) It is always a sunny day only if it is a rainy day. (d) No day is sunny. (e) Monday was sunny; therefore every day will be sunny. (f) It rained both Monday and Tuesday. (g) If some day is rainy, then every day will be sunny.
