Why is (R={(1,1),(1,2),(2,1)}) not reflexive on (A={1,2})?(R={(1,1),(1,2),(2,1)}) (A={1,2}) पर स्वपरक क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because ((2,2)) is missingक्योंकि ((2,2)) नहीं है
Step 1: Reflexivity needs self-pairs for both elements. Step 2: ((1,1)) is present, but ((2,2)) is missing. Step 3: One self-pair is not enough; all ((a,a)) pairs are required.चरण 1: स्वपरकता के लिए दोनों तत्वों के स्वयं वाले युग्म चाहिए। चरण 2: ((1,1)) है लेकिन ((2,2)) नहीं है। चरण 3: एक युग्म पूरा होना काफी नहीं, सभी ((a,a)) जरूरी हैं।
