sec2 A + (cosec2 A - 1) - (1 + tan2 A) - cot2 A = __
प्रयुक्त अवधारणा:
पाइथागोरस त्रिकोणमितीय सर्वसमिकाएँ:
cosec2 θ - 1 = cot2 θ
1 + tan2 θ = sec2 θ
गणना:
⇒ sec2 A + (cosec2 A - 1) - (1 + tan2 A) - cot2 A
त्रिकोणमितीय सर्वसमिकाओं के अनुसार मान रखने पर,
⇒ sec2 A + cot2 A - sec2 A - cot2 A = 0
इसलिए, sec2 A + cot2 A - sec2 A - cot2 A का आवश्यक मान 0 है।
अतः सही उत्तर विकल्प (2) है।
