Problem
\( \left(^{*}\right) \) Of the following, which is a solution to \( 2 \sin (2 x)=\sqrt{3} \) ? Select one: a. 0 b. \( \pi / 6 \) c. \( \pi / 4 \) d. \( \pi / 3 \) e. \( \pi / 2 \)
Solution
Step 1 ：\( 2 \sin (2 x)=\sqrt{3} \)
Step 2 ：\( \sin (2 x)=\frac{\sqrt{3}}{2} \)
Step 3 ：\( 2 x = \frac{\pi}{3}, \frac{2\pi}{3} \)
Step 4 ：\( x = \frac{\pi}{6}, \frac{\pi}{3} \)
