… ►In each case when $y=1$, the quantity multiplying ${R}_{C}$ supplies the asymptotic behavior of the left-hand side as the left-hand side tends to 0. …##### 2: 19.6 Special Cases

… ►Formulas involving $\mathrm{\Pi}(\varphi ,{\alpha}^{2},k)$ that are customarily different for circular cases, ordinary hyperbolic cases, and (hyperbolic) Cauchy principal values, are united in a single formula by using ${R}_{C}(x,y)$. … ►When $x$ and $y$ are positive, ${R}_{C}(x,y)$ is an inverse circular function if $$ and an inverse hyperbolic function (or logarithm) if $x>y$: …For the special cases of ${R}_{C}(x,x)$ and ${R}_{C}(0,y)$ see (19.6.15). …##### 4: 19.36 Methods of Computation

Section: 15.9(v) Complete Elliptic Integrals. Equations: (11.11.9_5), (11.11.13_5), Intermediate equality in (15.4.27) which relates to $F(a,a;a+1;\frac{1}{2})$, (15.4.34), (19.5.4_1), (19.5.4_2) and (19.5.4_3).

as $y\to 0+$, $p$ ($\ne 0$) real, we have added the constant term $\frac{-3}{p}{R}_{C}(z,p)$ and the order term $O\left(y\mathrm{ln}y\right)$, and hence $\sim $ was replaced by $=$.

The Kronecker delta symbols have been moved furthest to the right, as is common convention for orthogonality relations.

A number of additions and changes have been made to the metadata to reflect new and changed references as well as to how some equations have been derived.

The definition of ${R}_{C}(x,y)$ was revised in Notations.

##### 10: Software Index

This is software of narrow scope developed as a byproduct of a research project and subsequently made available at no cost to the public. The software is often meant to demonstrate new numerical methods or software engineering strategies which were the subject of a research project. When developed, the software typically contains capabilities unavailable elsewhere. While the software may be quite capable, it is typically not professionally packaged and its use may require some expertise. The software is typically provided as source code or via a web-based service, and no support is provided.

These are collections of software (e.g. libraries) or interactive systems of a somewhat broad scope. Contents may be adapted from research software or may be contributed by project participants who donate their services to the project. The software is made freely available to the public, typically in source code form. While formal support of the collection may not be provided by its developers, within active projects there is often a core group who donate time to consider bug reports and make updates to the collection.

An increasing number of published books have included digital media containing software described in the book. Often, the collection of software covers a fairly broad area. Such software is typically developed by the book author. While it is not professionally packaged, it often provides a useful tool for readers to experiment with the concepts discussed in the book. The software itself is typically not formally supported by its authors.

Such software ranges from a collection of reusable software parts (e.g., a library) to fully functional interactive computing environments with an associated computing language. Such software is usually professionally developed, tested, and maintained to high standards. It is available for purchase, often with accompanying updates and consulting support.
