How would I draw out the truth table for something with 3 things? (p, q and r). I am only used to doing 2 things (p and q) Here are the two things that I am supposed to check whether or not they are logically equivalent.
P = (p --> q) ^ (q --> r), Q = p --> r
All I need to know is how to set up the truth table, I can do the calculations myself.
What does "==" mean?
If it means "if and only if" then please learn to use LaTeX notation.
For example [TEX]\left( {p \Rightarrow q} \right) \Leftrightarrow \left( {\neg p \vee q} \right)[/TEX] gives .
Do you see why that is so much easier to read?
Why that is so much more professional?
Why that is then so much more helpful?
