Let R be a relation on X, If R is symmetric then xRy impliesyRx. If it is also transitive then xRy and yRx implies xRx.So whenver a relation is symmetric and transitive then it is also reflexive. What is wrong in this argument ? |

Answer» Solution :Let R is a relation on X.` If R is SYMMETRIC the `xRy implies yRx` If R is ALSO transitive then xRy and yRx `impliesxRx` ` implies` Whenever a relation is symmetric and transitive , then it is reflexive. This argument is wrong because the symmetry of R does not IMPLY dom R does not imply domR =Xand for reflexive `XRX AA x in X`. |
