The present work has the scope to show the relationship between four three-dimensional waves. This fact will be made in the form of coupling, using for it the Cauchy-Riemann conditions for quaternionic functions [#!BorgesZeMarcio!#], through certain Laplace's equation in [#!MaraoBorgesLP!#]. The coupling will relate those functions that determine the wave as well as their respective propagation speeds.

This paper presents an application of Laplace's equation obtained from a quaternionic function that satisfies the Cauchy-Riemann conditions determined earlier by Borges and Machado [#!BorgesZeMarcio!#]. Therefore, we show that it is possible to express in a single equation gravity, electric and magnetic potential fields, and this expression can only be provided due to a function that will be called here the coupling function.

The present work shows a coupling of electrical and gravitational fields through Cauchy-Riemann conditions for quaternions present in a previous paper [1]. It is also obtained an extended version of the Laplace-like equations for quaternions, now written in terms of both electric and gravitational fields.

The text argues that a linguistic analysis paired with the appreciation of the context of current social stands is highly legitimate, observing, however, that, in different situations, this so-called investigative-appreciative attitude has been transformed in actions and reactions that might become vulgarized in common place, or might even become disfigured in stupidity. The distortions in the assessment of the discourse of the other are now a widespread, the hunt for what is now conventionalized as the politically incorrect in language is just a sample of such a distortion. In this presentation, a number of cases of such a nature is analyzed against cases in which, inversely, the use of language is markedly polite, but the deviation of conduct is made more evident. The objective is to evaluate both cases via the role of intersubjectivity in the construal of discourse, aiming at verifying its conceptual counterpart, with special attention to evidence on the mutual conceptual engagement between interlocutors.
