          Exercise 4.42
Use the truth tree method to determine whether the following set of wffs produces a completed open tree or a closed tree.
1. $A \wedge (\neg A \wedge B)$
2. $A \wedge \neg (A \vee B)$
3. $A \wedge B, \neg (A \rightarrow B)$
4. $A \vee B, \neg A \wedge \neg B$
5. $\neg (A \rightarrow B), \neg (A \leftrightarrow B)$
6. $A \rightarrow \neg (A \wedge B), \neg \neg B \vee C$

Step 1

A branch is closed if it contains a wff and its negation. A tree is closed if all its branches are closed. A tree is open if at least one branch is open. A completed open tree means all possible decompositions have been applied, and at least one branch remains Show more…
