simplify (4cos(2x)-9sin(x)-4)/(sqrt(-cos(x)))

simplify

\frac{4 cos ( 2 x ) - 9 sin ( x ) - 4}{- cos ( x )}

\frac{4 cos ( 2 x ) - 9 sin ( x ) - 4}{i cos ( x )}

Solution steps

\frac{4 cos ( 2 x ) - 9 sin ( x ) - 4}{- cos ( x )}

- cos (x) = i cos (x)

= \frac{4 cos ( 2 x ) - 9 sin ( x ) - 4}{i cos ( x )}

\frac{x ^{2} - 11 x + 24}{x ^{2} + 5 x - 24}
