-(2cos(pi))/(sqrt(2-4sin(pi)))

- \frac{2 cos ( π )}{2 - 4 sin ( π )}

2

Solution steps

- \frac{2 cos ( π )}{2 - 4 sin ( π )}

Use the following trivial identity:

cos (π) = (- 1)

Use the following trivial identity:

sin (π) = 0

= - \frac{2 ( - 1 )}{2 - 4 \cdot 0}

Simplify

- \frac{2 ( - 1 )}{2 - 4 \cdot 0} : 2

= 2
