Описание: This lecture is for class 12 and covers to basic concepts regarding what is "relation" how it is linked to a set. How we define set and relation. Relation is a sub set of a given Set with defined composition. If relation between the elements is defined in such a way that we get empty set out of available elements in a given set then we have empty relation. For example if the given set is a class 12 of boys school and defined relation is that the two elements are brothers and sisy then we will fail to get any combination from the given set which can meet are required relation. This this becomes an empty relation. On the contrary if we find that all possible combinations of the given set meet are defined relation then it is a universal relation. This may appear abstract and dull, but the lecture attempts to explain this with neat examples. NCERT pattern has been followed in this lecture.
