WHAT IS A DOT?
THE ONLY TRUTH VALUES FOR p AND q FOR WHICH A CONJUNCTION IS TRUE

WHAT IS "p = T , q = F"?
THE TRANSLATION FOR: "IT IS FLASE THAT A WARM WINTER IMPLIES THAT THE SUN IS GETTING CLOSER TO THE EARTH"
WHAT IS "~(W → S)"?

WHAT IS TAUTOLOGY?
THE TRUTH VALUES FOR p AND q WHEN THE BICONDITIONAL IS TRUE
WHAT IS WHEN BOTH p AND q ARE THE SAME (EITHER BOTH T OR BOTH F)?
TO TEST FOR THIS, SET THE TRUTH VALUE OF ONE PREMISE TO TRUE AND THE OTHER TO FALSE AND SEE IF THAT LEADS TO CONTRADICTION
