Numerical integration

In analysis, numerical integration comprises a broad family of algorithms for calculating the numerical value of a definite integral, and by extension, the term is also sometimes used to describe the

Truncation error (numerical integration)

Truncation errors in numerical integration are of two kinds:
* local truncation errors – the error caused by one iteration, and
* global truncation errors – the cumulative error caused by many itera

Local linearization method

In numerical analysis, the local linearization (LL) method is a general strategy for designing numerical integrators for differential equations based on a local (piecewise) linearization of the given
