tan A + cot A = 2
கணக்கீடு:
கேள்வியின் படி,
எங்களிடம் டான் A + கட்டில் A = 2 உள்ளது
இருபுறமும் ஸ்கொயர், நாம் பெறுகிறோம்
⇒ (tan A + cot A)2 = (2)2
⇒ tan2 A + cot2 A + 2(tan A)(cot A) = 4
⇒ tan2 A + cot2 A + 2(tan A)(1/tan A) = 4
⇒ tan2 A + cot2 A + 2 = 4
⇒ tan2 A + cot2 A = 2
இப்போது,
2(tan2 A + cot2 A) = 2 × 2
⇒ 4
∴ 2(tan2 A + cot2 A) இன் மதிப்பு 4 ஆகும் .
