sin θ = 0.5 implies tan θ + cot θ is equal to :

  1. 2 : 3\sqrt{3}

  2. 3\sqrt{3} : 4

  3. 4 : 3\sqrt{3}

  4. 3\sqrt{3} : 2

Answer

Given,

⇒ sin θ = 0.5

⇒ sin θ = 510\dfrac{5}{10}

⇒ sin θ = 12\dfrac{1}{2}

⇒ sin θ = sin 30°

⇒ θ = 30°.

Substituting value of θ in tan θ + cot θ, we get :

⇒ tan θ + cot θ

⇒ tan 30° + cot 30°

13+3\dfrac{1}{\sqrt{3}} + \sqrt{3}

1+33\dfrac{1 + 3}{\sqrt{3}}

43\dfrac{4}{\sqrt{3}}

⇒ 4 : 3\sqrt{3}.

Hence, Option 3 is the correct option.
