Quizzes
Quiz 1 (due 24 January) (solution): Show that $P \rightarrow P$ is a tautology using a truth table. Also, show that $Q$ is a propositional consequence of $P \wedge Q$ using a truth table.
Quiz 2 (due 7 February) (solution): Prove $S$ from the premises $P \rightarrow Q$, $Q \rightarrow R$, $\neg R \vee S$, and $P$.
Quiz 3 (due 21 February) (solution): Prove $\forall x(Hx \longleftrightarrow Ix)$ from the premises $\forall x(Hx \rightarrow Ix)$ and $\forall x(Ix \rightarrow Hx)$.
Quiz 4 (due 21 March): Prove the following theorem in naive set theory (see notes from today below): $((x \subseteq y) \wedge (y \subseteq z)) \rightarrow x\subseteq z$.
Quiz 5 (due 15 April): Write the axioms of 3-line geometry and sketch a model of it.
Quiz 6 (due 15 April): Show that the axioms of 3-line geometry are independent by drawing appropriate models.
