Which expression is not defined?कौन सा व्यंजक परिभाषित नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\sin^{-1}2\)\(\sin^{-1}2\)
The expression \(\sin^{-1}x\) is defined only for \(x\in[-1,1]\), and \(2\notin[-1,1]\). In domain questions check each option quickly.\(\sin^{-1}x\) केवल \(x\in[-1,1]\) के लिए परिभाषित है और \(2\notin[-1,1]\)। डोमेन आधारित प्रश्नों में विकल्प तुरंत जांचें।
