# Math Help - Method of Stationary Phase

1. ## Method of Stationary Phase

Hi,

Could someone please help me with:

Use the method of stationary phase to find an asymptotic representation, valid as x tends to infinity.

$\int_{0}^{\pi/2}\left \frac{1}{\sqrt{ 1-\frac{2\theta}{\pi}} \right}\cos(x\cos\theta)d\theta$

Cheers,
