Derive the following using all known inferences rules and equivalences including QE. Remember that equivalences afford you greater power than derivation rules, because you are permtted to substitute equivalent sub formlas within a wff. For example, all the moves on the left below are legitimate inferences even though the first conditional is the main operator. However, it is important to remember that you must always be operating on a true self-contained wff. The moves on the right are not legitimate...
