JEE Mains · Maths · STD 12 - 2. inverse trigonometric function

\(\cos ^{-1}(\cos (-5))+\sin ^{-1}(\sin (6))-\tan ^{-1}(\tan (12))\) बराबर है (प्रतिलोम त्रिकोणमितीय फलन मुख्य मान लेते हैं।)

  1. A \(3 \pi-11\)
  2. B \(4 \pi-9\)
  3. C \(4 \pi-11\)
  4. D \(3 \pi+1\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(4 \pi-11\)

Step-by-step Solution

Detailed explanation

\(\cos ^{-1}(\cos (-5))+\sin ^{-1}(\sin (6))-\tan ^{-1}(\tan (12))\) \(\Rightarrow(2 \pi-5)+(6-2 \pi)-(12-4 \pi)\) \(\Rightarrow 4 \pi-11\)
