Question:


If sec θ - tan θ = \(\frac{1}{\sqrt {3 }}\), then value of sec θ is?

Options:

1

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

3\(\sqrt {3 }\)

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

Correct Answer:

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

Explanation:

sec θ - tan θ = \(\frac{1}{\sqrt {3 }}\)  ............(i)

then sec θ + tan θ = \(\sqrt {3}\)

adding the equation

2 sec θ = \(\sqrt {3 }\) + \(\frac{1}{\sqrt {3 }}\)

⇒ 2sec θ = \(\frac{4}{\sqrt {3 }}\) or sec θ = \(\frac{2}{\sqrt {3 }}\)
