##### 5: 28.8 Asymptotic Expansions for Large $q$

…
►With additional restrictions on $z$, uniform asymptotic approximations for solutions of (28.2.1) and (28.20.1) are also obtained in terms of elementary functions by re-expansions of the Whittaker functions; compare §2.8(ii).
►Subsequently the asymptotic solutions involving either elementary or Whittaker functions are identified in terms of the Floquet solutions
${\mathrm{me}}_{\nu}(z,q)$ (§28.12(ii)) and modified Mathieu functions ${\mathrm{M}}_{\nu}^{(j)}(z,h)$ (§28.20(iii)).

##### 6: 32.2 Differential Equations

…
►For arbitrary values of the parameters $\alpha $, $\beta $, $\gamma $, and $\delta $, the general solutions of ${\text{P}}_{\text{I}}$–${\text{P}}_{\text{VI}}$ are

*transcendental*, that is, they cannot be expressed in closed-form elementary functions. However, for special values of the parameters, equations ${\text{P}}_{\text{II}}$–${\text{P}}_{\text{VI}}$ have special solutions in terms of elementary functions, or special functions defined elsewhere in the DLMF. …##### 7: 2.8 Differential Equations with a Parameter
