Solve \(\tan (x)+\sec (x)=\sqrt{3}, x \in[0,2 \pi]\)
Solve \(\tan (x)+\sec (x)=\sqrt{3}, x \in[0,2 \pi]\)
- \(\frac{\pi}{3}\)
- \(\frac{\pi}{6}\)
- \(\frac{13 \pi}{6}\)
- \(\frac{6 \pi}{13}\)
Solution
Given trigonometric equation is
\(\begin{aligned}
& \tan x+\sec x=\sqrt{3}, x \in[0,2 \pi] \\
& \therefore \quad \sec x-\tan x=\frac{1}{\sqrt{3}}
\end{aligned}\)
So, \(2 \tan x=\sqrt{3}-\frac{1}{\sqrt{3}}\)
\(\Rightarrow 2 \tan x=\frac{2}{\sqrt{3}} \Rightarrow \tan x=\frac{1}{\sqrt{3}} \Rightarrow x=\frac{\pi}{6}\) or \(\frac{7 \pi}{6}\)
Hence, option (b) is correct.
