What was discovered
A method that approximates a function using the ratio of two polynomials whose power series matches that of the original function; it improves on the Taylor series approximation and converges where the Taylor series does not.
What it led to
- Computer-assisted numerical calculation
- Dynamical systems and control modeling
- Transcendental number theory
- Rational approximation in computational physics
