Answer:
c, a, b
Step-by-step explanation:
Given
See attachment for matrices
(a)
The determinant of the matrix is:
Using trigonometry ratio, we have:
(b)
The determinant of the matrix is:
(c)
The determinant of the matrix is:
In complex numbers
So:
<em>So, the order of the determinants is: c, a, b</em>
