§10.22(ii) Integrals over Finite Intervals

Notes:: For (10.22.8)–(10.22.12) see Luke (1962, pp. 51–53). To verify (10.22.13) construct the expansion of the left-hand side in powers of by use of (10.2.2), followed by term-by-term integration with the aid of (5.12.5) and (5.12.1). Then compare the result with the corresponding expansion of the right-hand side obtained from (10.8.3). Next, the result $\int_{0}^{{2\pi}}\mathop{J_{{2\nu}}\/}\nolimits\!\left(2z\mathop{\sin\/}% \nolimits\theta\right)e^{{\pm 2i\mu\theta}}d\theta=\pi e^{{\pm i\mu\pi}}% \mathop{J_{{\nu+\mu}}\/}\nolimits\!\left(z\right)\mathop{J_{{\nu-\mu}}\/}% \nolimits\!\left(z\right)$ , $\realpart{\nu}>-\tfrac{1}{2}$ , is proved in a similar manner with the aid of (5.12.6) in place of (5.12.5)—from which (10.22.14) and (10.22.15) both follow. (10.22.17) follows by combining (10.22.13) and (10.2.3); (10.22.16) is a special case of (10.22.14). For (10.22.18) replace $\theta$ by $\tfrac{1}{2}\pi-\theta$ and set $\mu=n$ in (10.22.17); then apply (10.2.3) and let $\nu\to 0$ . For (10.22.19), (10.22.22), (10.22.25), (10.22.26) see Watson (1944, Chapter 12). (In the case of (10.22.25), page 374 of this reference lacks a factor $\frac{1}{2}$ on the right-hand side.) The verification of (10.22.20) is similar to that of (10.22.13), the role of (5.12.5) now being played by (5.12.2). For (10.22.21) combine (10.2.3) and (10.22.20). For (10.22.23) and (10.22.24) see Luke (1962, p. 302 (36) and p. 303 (39), respectively). For (10.22.27) see Watson (1944, p. 151). For (10.22.28), (10.22.29) differentiate and use (10.6.2). For (10.22.30) with $n\geq 1$ it follows by differentiation and use of (10.6.2) that the left-hand side equals $\int_{0}^{x}t^{{-1}}{\mathop{J_{{n}}\/}\nolimits^{{2}}}\!\left(t\right)dt-% \tfrac{1}{2}{\mathop{J_{{n}}\/}\nolimits^{{2}}}\!\left(x\right)$ ; application of Watson (1944, p. 152) yields the second result, then for the first result refer to (10.23.3). Some modifications of the proof of (10.22.30) are needed when . For (10.22.31)–(10.22.35) see Watson (1944, p. 380). For (10.22.36) replace by , substitute for $t^{\alpha}$ via (10.23.15) (with replaced by , and $\nu$ replaced by $\alpha$ ), and then apply (10.22.34). For (10.22.37) use (10.22.4) and (10.22.5); a similar proof applies to (10.22.38) after replacing $\mathop{\mathscr{C}_{{\mu\pm 1}}\/}\nolimits\!\left(az\right)$ and $\mathscr{D}_{{\mu\pm 1}}(bz)$ by $\mp{\mathop{\mathscr{C}_{{\mu}}\/}\nolimits^{{\prime}}}\!\left(az\right)$ and $\mp\mathscr{D}_{{\mu}}^{{\prime}}(bz)$ , respectively, by means of (10.6.2).

Sufficient conditions for the validity of (10.22.77) are that $\int_{0}^{\infty}|f(x)|dx<\infty$ when $\nu\geq-\tfrac{1}{2}$ , or that $\int_{0}^{\infty}|f(x)|dx<\infty$ and $\int_{0}^{1}x^{{\nu+\frac{1}{2}}}|f(x)|dx<\infty$ when $-1<\nu<-\tfrac{1}{2}$ ; see Titchmarsh (1986a, Theorem 135, Chapter 8) and Akhiezer (1988, p. 62).
