What looks like an impossible integral…
turns into a precise asymptotic formula:
\[ \mathrm{Ai}(z) \sim \frac{1}{2\sqrt{\pi}\, z^{1/4}} \, e^{-\frac{2}{3} z^{3/2}} \]

The secret? Geometry in the complex plane.

A Small Taste from My New Book: Season 2 Episode 12

Explorations in analytic number theory, asymptotic analysis, and unsolved problems, written by a mathematician and software engineer.

Rigorous treatments of the method of #steepestdescent and the method of stationary phase, amongst others, are based on the Riemann–Lebesgue lemma.
asymptotic representations can then be derived by a standard application of the method of #steepestdescent
