How would I solve this?
snow_tiger [21]

Answer:

- \frac{1}{2}

Step-by-step explanation:

Given the 2 by 2 matrix

\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]

The determinant = ad - bc

For the given matrix

a = \frac{1}{2}, b = \frac{\sqrt{3} }{2}, c = \frac{\sqrt{3} }{2}, d = \frac{1}{2} , thus

ad - bc = \frac{1}{2} × \frac{1}{2} - ( \frac{\sqrt{3} }{2} × \frac{\sqrt{3} }{2} ) = \frac{1}{4} - \frac{3}{4} = - \frac{1}{2}
