Step-by-step explanation:
दिया है: व्यंजक
(sin² 63° + sin² 27°)/(cos² 17° + cos² 73°)
17 को के रूप में और 17 को के रूप में निरूपित कीजिए
→ [sin (90° - 27°)² + sin² 27]/[cos(90° - 73°)²+ cos² 73°]
कोटिपूरक कोण के सूत्र का प्रयोग कीजिये
और,
sin (90° – ⍉) = cos ⍉ और cos (90° – ⍉) = sin ⍉
→ (cos² 27° + sin² 27°)/(sin² 73° + sin² 73)
मूल त्रिकोणमितीय सर्वसमिका sin ⍉ + cos ⍉ = 1 का प्रयोग कीजिए
→ [(cos² 27° + sin² 27°)/(sin² 73° + sin² 73)] = 1/1
→ [(cos² 27° + sin² 27°)/(sin² 73° + sin² 73)] = 1
दिये गये व्यंजक का मान है- [(sin² 63° + sin² 27°)/(cos² 17° + cos² 73°)] = 1.
