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...
