AsymptoticDSolveValue

AsymptoticDSolveValue[eqn, f, x -> x0] computes an asymptotic approximation to the differential equation eqn for f[x] centered at x0.

AsymptoticDSolveValue[{eqn1, eqn2, ...}, {f1, f2, ...}, x -> x0] computes an asymptotic approximation to a system of differential equations.

AsymptoticDSolveValue[eqn, f, x, ε -> ε0] computes an asymptotic approximation of f[x, ε] for the parameter ε centered at ε0.

Examples
