If tan θ = 3 and θ lies in third quadrant, then the value of sin θ is
Choice (d) is correct. Given that , tan θ = 3 we know that, sec² θ = 1 + tan² θ ⇒ sec² θ = 1 + 3² = 1 + 9 = 10 ⇒ cos² θ = 1/10 We know that sin² θ = 1 - cos² θ sin² θ = 1 - 1/10 = 10 - 1/10 = 9/10 ⇒ sin θ = ± √9/10 = ± 3/√10 ⇒ sin θ = -3√10 This question related to Chapter 3 maths Class 11th NCERT.Read more
Choice (d) is correct. Given that , tan θ = 3
we know that, sec² θ = 1 + tan² θ
⇒ sec² θ = 1 + 3² = 1 + 9 = 10 ⇒ cos² θ = 1/10
We know that sin² θ = 1 – cos² θ
sin² θ = 1 – 1/10 = 10 – 1/10 = 9/10
⇒ sin θ = ± √9/10 = ± 3/√10 ⇒ sin θ = -3√10
