The value of $\left|\begin{array}{ll}\frac{\sqrt{3}}{2} & \frac{1}{2} \\ \frac{\sqrt{3}}{2} & \frac{1}{2}\end{array}\right|$
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) - 0
$\left|\begin{array}{ll}\frac{\sqrt{3}}{2} & \frac{1}{2} \\ \frac{\sqrt{3}}{2} & \frac{1}{2}\end{array}\right|=\frac{\sqrt{3}}{2}×\frac{1}{2}-\frac{\sqrt{3}}{2}×\frac{1}{2}=0$
