## Homework Statement

[tex]\int_{\frac{5\pi}{6}}^{\pi}\frac{\cos^{4}x}{\sqrt{1-\sin{x}}}dx[/tex]

## Homework Equations

[tex]\cos^{2}x=\frac{1+\cos{2x}}{2}[/tex]

## The Attempt at a Solution

i used the above equation, then expanded it all out and multiplied by the denominator and hoped i would then be able to do a simple substitution that would give me an antiderivative after integrating but that hasn't been working for me

any ideas?
