# §9.11 Products

## §9.11(i) Differential Equation

where and are any solutions of (9.2.1). For example, , , , . Numerically satisfactory triads of solutions can be constructed where needed on or by inspection of the asymptotic expansions supplied in §9.7.

## §9.11(iii) Integral Representations

For an integral representation of the Dirac delta involving a product of two functions see §1.17(ii).

For further integral representations see Reid (1995, 1997a, 1997b).

## §9.11(iv) Indefinite Integrals

For , , , where is any positive integer, see Albright (1977). For related integrals see Gordon (1969, Appendix B).

For any continuously-differentiable function

## §9.11(v) Definite Integrals

For further definite integrals see Prudnikov et al. (1990, §1.8.2), Laurenzi (1993), Reid (1995, 1997a, 1997b), and Vallée and Soares (2010, Chapters 3, 4).
