Let
![u=\sin x](https://tex.z-dn.net/?f=u%3D%5Csin%20x)
, then
![\mathrm du=\cos x\,\mathrm dx](https://tex.z-dn.net/?f=%5Cmathrm%20du%3D%5Ccos%20x%5C%2C%5Cmathrm%20dx)
. Now
![\displaystyle\int\frac{\cos x}{\sqrt{\sin x}}\,\mathrm dx=\int\frac{\mathrm du}{\sqrt u}=\int u^{-1/2}\,\mathrm du](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint%5Cfrac%7B%5Ccos%20x%7D%7B%5Csqrt%7B%5Csin%20x%7D%7D%5C%2C%5Cmathrm%20dx%3D%5Cint%5Cfrac%7B%5Cmathrm%20du%7D%7B%5Csqrt%20u%7D%3D%5Cint%20u%5E%7B-1%2F2%7D%5C%2C%5Cmathrm%20du)
