preperation for logical form & equivalence

Introduction - Logic is the study and analysis of valid arguments. The arguments are in the form of statements or propositions, which are either true or false, but not both. There are also some statements, which appear to be true and false at the same time. They are called parad..

Introduction - We are already familiar with set theory and mathematical logic from earlier classes. It has already been seen that there is a similarity between the laws stated in set theory and the mathematical logic. The operations 'union', 'intersection' and 'complement' on se..

The word 'Induction' means method of reasoning from individual cases to general ones or from observed instances to unobserved ones. Many important mathematical formulae are such that a result is formed by some means which does not provide for a direct proof. Mathematical Induction is a pr..

. In reverse biasing, the conduction across the p-n junction does not takes place due to majority carriers but takes place due to minority carriers if the voltage of external battery is large. The size of the depletion region increase. The resistance of the p-n junction becomes high in reverse bias..

.e., Le systeme internationale d' unites, is a new, comprehensive and rationalised system of units, accepted by the 11 t h conference of weights and measures in 1960. It is used in science and technology all over the world, because of the following advantages over others. The units are more lo..
