Second Assignment

This assignment comprises a total of 60 marks, and is worth 15% of the overall
assessment. It should be completed, accompanied by a signed cover sheet, and handed
in at the lecture on Wednesday 28 May. Acknowledge any sources or assistance.
Please note that the ﬁrst question is about the Proposition Calculus (not the Predicate Calculus). You should ﬁnd part (a) straightforward. Part (b) is diﬃcult and
optional. Students that complete it successfully may be awarded bonus marks, and
there may be a prize for the best correct answer.
1. A positive well-formed formula (positive wﬀ) in the Propositional Calculus is
a well-formed formula that avoids all use of the negation symbol ∼ .
(a) Use induction on the length of a wﬀ to prove that if W = W (P1 , . . . , Pn )
is a positive wﬀ in terms of propositional variables P1 , . . . , Pn , then
V (P1 ) = . . . = V (Pn ) = T

implies V (W ) = T .
(5 marks)

(b) Prove that if W = W (P1 , . . . , Pn ) is any wﬀ in the Propositional Calculus
such that V (P1 ) = . . . = V (Pn ) = T implies V (W ) = T , then W is
logically equivalent to a positive wﬀ.
(optional, bonus marks)

2. Use the rules of deduction in the Predicate Calculus to ﬁnd formal proofs for
the following sequents (without invoking sequent or theorem introduction):
(a)

(∃x)(∃y)(∀z) K(y, x, z) ⊢ (∀z)(∃y)(∃x) K(y, x, z)

(b)

(∀x)(G(x) ⇒ F (x))

(c)

(∀x)(∀y)(∃z) R(x, z) ∧ R(y, z)

(d)

(∀x)(∀y)(∀z) R(x, y) ∧ R(y, z) ⇒ R(x, z) ,

(∃x) ∼ F (x) ⇒ (∃x) ∼ G(x)
⊢ (∀x)(∃y) R(x, y)

(∀x)(∀y)(∃z) R(x, z) ∧ R(z, y)

(∀x) R(x, x)
(21 marks)

3. Consider the following well-formed formulae in the Predicate Calculus:
W1
W2
W3

=

=

=

(∃x)(∃y) R(x, y)

(∀x)(∀y) R(x, y) ⇒ ∼ R(y, x)

(∀x)(∀y) R(x, y) ⇒ (∃z) R(z, x) ∧ R(y, z)

Prove that any model in which W1 , W2 and W3 are all true must have at least
3 elements. Find one such model with 3 elements.
(6 marks)
4. Let R = Z[x] and
I = 2Z + xZ[x] ,
the subset of R consisting of polynomials with integer coeﬃcients with even
constant terms. Verify that I is an ideal of R. Show that I not a principal
ideal.
(8 marks)
5. Let R = Z3 [x]/(x2 − x − 1)Z3 [x], so we may write
R = { 0 , 1 , 2 , x , x + 1 , x + 2 , 2x , 2x + 1 , 2x + 2 } ,
where we identify equivalence classes with remainders after division by the
polynomial x2 − x − 1. Then R is a commutative ring with identity. Construct
the multiplication table for R and use it to explain why R is a ﬁeld. Now ﬁnd
a primitive element, that is, an element a ∈ R such that all nonzero elements
of R are powers of a.
(8 marks)

6. In each case below, if it helps, you may identify the ring with remainders after
division by x2 + x + 1, so that the elements become linear expressions of the
form a + bx where a, b come from Z3 in part (a) or from R in part (b).
(a) Explain why R = Z3 [x]/(x2 + x + 1)Z3 [x] is not a ﬁeld.
(b) Prove that F = R[x]/(x2 + x + 1)R[x] is isomorphic to C, the ﬁeld of
complex numbers.
(12 marks)

Deduction Rules for the Propositional and Predicate Calculi

The Ten Rules of Deduction for the Propositional Calculus:

(1)        Rule of Assumptions (A): Any wﬀ may be written down as an assump-tion, depending only on itself.

(2)         Modus Ponens (MP): Given V and V W , we may deduce W , depending on the pooled assumptions for V and V W .

(3)         Modus Tollens (MT): Given W and V W , we may deduce V , depending on the pooled assumptions for W and V W .

(4)       Double Negation (DN): Given ∼∼ W , we may deduce W , and given W we may deduce ∼∼ W , in each case depending on the same underlying assumptions.

(5)       Conditional Proof (CP): Given V , introduced at some earlier step by Rule of Assumptions, and given W , relying on V as an underlying assump-tion, we may deduce V W , discharging the assumption V , but relying on any remaining assumptions used to deduce W from V .

(6) -Introduction ( I): Given V and W , we may deduce V W , relying on the pooled assumptions for V and W .

(7)        -Elimination ( E): Given V W , we may deduce V or deduce W , relying on assumptions for V W .

(8)        -Introduction ( I): Given V , we may deduce V W or deduce W V for any W , relying on the assumptions for V .

 (9) ∨-Elimination (∨ E): Given V  ∨ W  and two deductions of C , firstly from V , introduced by Rule of Assumptions, and secondly from W , intro-

duced by Rule of Assumptions, we may deduce C again, but from V W , discharging the assumptions V and W , but pooling any assumptions for

V    W  and any assumptions used to deduce C from V and C from W .

(10)         Reductio ad Absurdum (RAA): Given V , introduced at some earlier step by Rule of Assumptions, and given the contradiction W W , relying on V as an underlying assumption, we may deduce V , discharging the assumption V , but relying on any remaining assumptions used to deduce

W  W from V .

The Four Extra Rules of Deduction for the Predicate Calculus:

(11)          -Introduction ( I): Given a wﬀ W (B) , where B is a constant symbol that occurs at least once, we may deduce (X) W (X) , where X is a new variable that does not appear in W (B) and replaces B uniformly throughout W (B) , relying on the assumptions for W (B) , provided the symbol B does not appear in any wﬀ in this list of underlying assumptions.

(12)          -Elimination ( E): Given a wﬀ (X) W (X) , we may deduce W (B) , where B is a constant symbol replacing X uniformly throughout W (X) , re-lying on assumptions for (X) W (X) .

(13)         -Introduction ( I): Given a wﬀ W (B) , where B is a constant symbol that occurs at least once, we may deduce (X) W (X) , where W (X) results from W (B) by replacing at least one occurrence of B by X, relying on the assumptions for W (B) .

(14) -Elimination ( E): Given a wﬀ (X) W (X) and a deduction of C from W (B), introduced by Rule of Assumptions, where B is a new constant symbol that replaces X uniformly throughout W (X) , we may deduce C again, but from (X) W (X) , discharging the assumption W (B) , but pooling any assumptions for (X) W (X) and any assumptions used to deduce C from W (B), provided B does not appear in C or in any of these underlying assumptions.

Hi,

I need homework help but don't have time to do it myself due overtime at work. I need someone to complete it for me. I see a couple of places online but I would like someone local. Please see attachment. I also have the book for the reference notes mentioned in the study material if needed. The lessons are from Richard J Fowler Electricity Principles & Applications 8th edition. I need questions in unit 3 (30-36) completed and unit 4 (29-37). If you can help please send me your quote.

Thanks,
