Solving the Hyperbolic Equation in Elementary Functions

The classical problem about oscillation of music strings is considered. Its solution can be represented as Fourier series, and also as elementary functions. Such a representation is valid only over the fi of real numbers and doesn't belong Liouville theory. This circumstance lids to several diffi at work with the solutions in CAS. A typical example from CAS Maple is considered.
