**Integral, hint plz**

[tex]\int\frac{\cos^{\frac{5}{2}}x}{\sqrt{\sin{x}}}dx[/tex]

Tried: splitting it up, trig identities = no go!

[tex]\int\frac{\cos{x}\cos^{\frac{3}{2}}x}{\sqrt{\sin{x}}}dx[/tex]

Broke up cosine cubed then ended up realizing I would have a cosine left over so that wasn't a good idea.

[tex]\int\cos^{2}x\sqrt{\cot{x}}dx[/tex]

Then my world crumbled.
