WebMar 9, 2024 · The tree method for predicate logic works in exactly the same way, with just one change: Each branch is no longer a way of developing a line of a truth table which will make all the sentences along the branch true. Instead, a branch is a way of developing an interpretation which will make all the sentences along the branch true.

WebHowever, the conclusion has nothing to do with the premises (completely different variables). I'm fairly certain that this makes the argument invalid, since the conclusion does not necessarily follow from the premises, but I have no idea how to show this/describe this by means of a truth tree (Required for a homework assignment).
