- More Derivations (using all rules)
- Derivations for Deductive Concepts (using all rules) So far we've used derivations to show that a conclusion can be
*validly*derived. This problem shows how we can use derivations to test other deductive concepts -- like logical truth and logical equivalence. Pay close attention to the directions to get the idea. If it still seems unclear, check out the Logic Café on derivation tests for our deductive concepts.
