Salim,
How are you proving these logical equalities, by truth tables or other means?
Alan G.
Salim,
I will assume you must use truth tables. You need to make a table showing all possible truth values for p and q, then find the truth values for p↔q, p→q, q→p, and (p→q)∧(q→p). If you do not know how to do this, I cannot really help you further. Some logic textbooks DEFINE p↔q to mean that both p→q and q→p are true together. If you want to PROVE this, you will need to dig deeper into this statement.
Give me more feedback about this if you want it. It is late where I am now and I cannot help you until you tell me carefully what you expect of me, okay?
