Question

Find the general solution of the following equation:

\[\sqrt{3} \sec x = 2\]
Sum
Advertisements

Solution

We have:

\[\sqrt{3} \sec x = 2\]
⇒ \[\sec x = \frac{2}{\sqrt{3}}\] (or) 
\[\cos x = \frac{\sqrt{3}}{2}\]
The value of x satisfying \[\cos x = \frac{\sqrt{3}}{2}\] is \[\frac{\pi}{6}\].
∴ \[\cos x = \frac{\sqrt{3}}{2}\]
⇒ \[\cos x = \cos\frac{\pi}{6}\]
⇒ \[x = 2n\pi \pm \frac{\pi}{6}\],
\[n \in Z\]
