Chapter 2- प्रतिलोम त्रिकोणमितीय फलन (Inverse Trigonometric Functions) Ex-2.2 Interview Questions Answers

Question 1 : निम्नलिखित को सिद्ध कीजिए–

Answer 1 :

माना sin-1x = θ sin θ = x
पुनः sin 3θ = 3 sin3 θ – 4 sin θ
sin 3θ = 3x – 4x3
3θ = sin-1(3x– 4x3)
3sin-1x =sin-1(3x – 4x3) इति सिद्धम्

Question 2 :

Answer 2 :

माना cos-1 x = θ cosθ = x
cos 3θ = 4cos3θ– 3 cos θ
cos 3θ = 4x3 –3x
3θ = cos-1(4x3 –3x)
3cos-1x =cos-1(4x3 – 3x) इति सिद्धम्
