Question 15 The graph drawn below depicts (A) 𝑦=〖𝑠𝑖𝑛〗^(−1) 𝑥 (B) 𝑦=〖𝑐𝑜𝑠〗^(−1) 𝑥 (C) 𝑦=〖𝑐𝑜𝑠𝑒𝑐〗^(−1) 𝑥 (D) 𝑦=〖𝑐𝑜𝑡〗^(−1) 𝑥 We can solve this using options From graph For x = −1, y = 𝜋 For x = 0, y = 𝜋/2 For x = 1, y = 0 Checking all options for x = −1, 0, 1 For x = −1 Option (A) - y So, the correct answer is (B) Question 15 The graph drawn below depicts (A) y=sin^(−1) x (B) 𝑦=〖𝑐𝑜𝑠〗^(−1) 𝑥 (C) 𝑦=〖𝑐𝑜𝑠𝑒𝑐〗^(−1) 𝑥 (D) 𝑦=〖𝑐𝑜𝑡〗^(−1) 𝑥 We can solve this using options From graph For x = −1, y = 𝜋 For x = 0, y = 𝜋/2 For x = 1, y = 0 If we do normal trigonometry, then this basically means, For θ = 𝜋, then __ θ = −1 For θ = 𝜋/2, then __ θ = 0 For θ = 0, then __ θ = 1 Since cos 0 = 1 And, cos 𝜋/2 = 0 ∴ This is graph of 𝒚=〖𝒄𝒐𝒔〗^(−𝟏) 𝒙 So, the correct answer is (B)
