- from J.P. Fitch, International Conference on Computer Algebra and
its Applications in Theoretical Physics, p. 262-275, Dubna, (1985).
- solution of a series in a small parameter
- zeroth order solution , -th order solution

- resulting iteration scheme

- another example: the Kepler equation
- zeroth order solution -th order solution

- final solution in the form of Fourier series

- Fourier series are used by specialized computer algebra systems
such as CAMAL and TRIGMAN
