Question

which of the following stament is incorrect sin teta =-_ 1/5 cos teta =1 secteta =1/2 tan teta =20
​

Answer 1

Answer:

C. sec θ = ½ Explanation: According to the question, We know that, a) sin θ = – 1/5 is correct since Sin θ ∈ [-1,1] b) cos θ = 1 is correct since Cos θ ∈ [-1,1] c) sec θ = ½ ⇒ (1/cos θ) = ½ ⇒cos θ=2 is incorrect since Cos θ ∈ [-1,1] d) tan θ = 20 is correct since tan θ ∈ R. Thus, option (C) sec θ = ½ is the correct answerRead more on Sarthaks.com - https://www.sarthaks.com/892286/which-of-the-following-is-not-correct-a-sin-1-5-b-cos-1-c-sec-d-tan-20
