Tautology
A compound statement is said to be a tautology, if it is always true for all possible combinations of the truth values of its components. A tautology is also called a theorem or a logically valid statement patter..
Method 1:
Construct the truth table of the conditional P 1 P 2 P 3 .... P m Q and find out whether it is a tautology or not. If it is a tautology then the argument is valid otherwise it is said to be inval..

If a compound proposition which is always false for all possible combination of the truth values, of its components then it is called a contradiction. Consider tw..

Test the validity of the following argument. P 1 : p q P 2 : q p, Q:p q To test the validity of the argument, we have to show P 1 P 2 Q is a tautology. Since the truth value of the last column are not all T..

Summary - A Boolean algebra is a set B with two distinct elements, along with the binary operations '+' and '.' and a unary operation (') which satisfy closure property, commutative property, existence of unit element, distributive property for both the binary operations. Moreover, for all x B, the..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
