Question:

If sin 4θ = \(\frac{\sqrt {3 }}{2}\), then find the value of tan (75° - θ).

Options:

\(\sqrt {3 }\)

\(\frac{1}{\sqrt{3}}\)

\(\frac{1 + \sqrt {3}}{2 \sqrt {2 }}\)

1

Correct Answer:

\(\sqrt {3 }\)

Explanation:

sin4θ = \(\frac{\sqrt {3}}{2}\)

⇒ 4θ = 60° ⇒ θ = 15°

tan (75° - 15)° = tan 60° = \(\sqrt { 3}\)
