If p then q if q then r therefore if p then r
If p then q if q then r therefore if p then r- ~p ^ (~q ^ r) v (q ^ r) v (p ^ r) and your rearrangement is ~p ^ (p ^ r) v (~q ^ r) v (q ^ r) As (q ^ r) is common to both of these expressions, you are effectively saying that ~p ^ (~q ^ r) v (p ^ r) ≡ ~p ^ (p ^ r) v (~q ^ r) which is NOT the case There is a proof in a previous thread that converts the two expressions (P → Q)∧ (Q → R) and (P → R)∧ (P ↔ Q) ∨ (R ↔ Q) to a CNFformula thereby proving their equivalencies I am approaching the proof from an entirely different proof technique and am stuck Instead of using truth tables, or converting these two expressions to the same CNF/DNFformulas I'd rather prove

It is true that given P, Q and ( P → Q) → R, you can deduce R You can see that with truth tables, for example However this requires logical rules that go beyond modus ponens This has a mathematical consequence this deduction is only valid in logics where those extra rules are available (such as classical logic) Transcript Example 24 If p,q,r are in GP and the equations, px2 2qx r = 0 and dx2 2ex f = 0 have a common root, then show that (d )/p, (e )/q, (f )/r are in AP It is given that p, q, r are in GP So, their common ratio is same / = / q2 = pr Solving the equation px2 2qx r = 0 For ax2 bx c roots are x = ( ( 2 4 ))/2 Here a = p, b = 2q & c = r Hence the roots of equationAnd the conclusion is ~r→~p We then create truth tables for both premises and for the conclusion

Indeed, (( P → Q ) ∨ ( Q → R )) should be the last line of your proof, not the first So, your whole setup for the proof is not good So, your whole setup for the proof is not good In his book, Tomassi lays out what he calls the 'golden rule' This sort of logical proof can easily be written in straight term mode though example (p q r Prop) (p ∨ q) ∧ (p ∨ r) → p ∨ (q ∧ r) = λ hpq, hpr , orelim hpq orinl $ λ hq, orelim hpr orinl $ λ hr, orinr hq, hr The "duplication" now is just the fact that the function orinl shows up twice My feeling is that because p P, Q, and R are three points P, Q, and Rare three points in a plane, and R does not lie on line PQ Which of the following is true about the set of all points in the plane that are the same distance from all three points?
