Mam actually I have a doubt in relationship anf functions chapter my doubt is Question will be asked to check wheather the retion is refexive symmetric.... Mam my doubt is agar wo diya hua relation agar refexive ya symmetric nahi hua to sirf ek example dene se kafi hai For example in exercise 1.1 Question no 1 subquestion 3 R will be {(1, 1)(1, 3), (1, 4),(1, 5),(1, 6),(2,4) (2, 6) (3,3),(3, 6), (4, 4),(5, 5),(6, 6) } So my doubt is as per definition.in this example (2, 4) belongs to r but (4, 2) does not belong to r Sirf ek reason dene se kafi hai...?? Maam Or wheather we have to write all the orderpairs
