# Asymptotics

Asymptotics is the calculus of approximations. It is used to solve hard problems that cannot be solved exactly and to provide simpler forms of complicated results, from early results like Taylor's and Stirling's formulas to the prime number theorem. It is extensively used in areas such as number theory, combinatorics, numerical analysis, analysis of algorithms, probability and statistics, special functions and modern physics. The Wolfram Language makes the language of asymptotics widely available and accessible. The language design makes it easy and natural to use by a wide audience. Extensive documentation and examples make it easy to learn and use in a variety of scenarios. Advanced algorithms make it actually work for an extensive range of problems.
