This theorem also provides a basis for the Risch algorithm for determining (with difficulty) which elementary functions have elementary antiderivatives.Įxamples of functions with nonelementary antiderivatives include: A theorem by Liouville in 1835 provided the first proof that nonelementary antiderivatives exist. a function constructed from a finite number of quotients of constant, algebraic, exponential, trigonometric, and logarithmic functions using field operations). In mathematics, a nonelementary antiderivative of a given elementary function is an antiderivative (or indefinite integral) that is, itself, not an elementary function (i.e. JSTOR ( December 2009) ( Learn how and when to remove this template message).Unsourced material may be challenged and removed.įind sources: "Nonelementary integral" – news If only concerned about the neighborhood very close to the origin, the (n2) approximation represents the sine wave sufficiently, and no higher. Please help improve this article by adding citations to reliable sources. Taylor series are extremely powerful tools for approximating functions that can be difficult to compute otherwise, as well as evaluating infinite sums and integrals by recognizing Taylor series. This article needs additional citations for verification. ![]()
