Approximation of analytic functions by Airy functions. (English) Zbl 1155.34002
The author solves the inhomogeneous Airy differential equation by the power series method and applies this result to estimate the error bound occuring when any analytic function is approximated by an appropriate Airy function, i.e. a solution of the homogeneous Airy differential equation.
