Extended mixed AKNS-lund-regge model and its self-similarity reduction
(2014-01-01)
We discuss the relation between the self-similarity reduction of the generalized mixed mKdV-sinh-Gordon model and the fourth-order equation obtained by Kudryashov in J. Phys. A: Math. Theor. 35 (2002) 93-99. Also, it is ...
Equações do segundo grau e mudança de variáveis
(Revista Ciências e Natura, 2015)
This article will present part of a Master Thesis (Profmat, 2014), which sought to assist in improving teaching practice math teacher, this practice in recent years ceased to be investigative and also became quite mechanical, ...
Positive solutions for an elliptic equation in an annulus with a superlinear nonlinearity with zeros
(Wiley-VCH Verlag GmbHWeinheim, 2014-07)
We study existence, multiplicity, and the behavior, with respect to λ, of positive radially symmetric solutions of − 'delta'u = λh(x, u) in annular domains in 'R POT.N', N ≥ 2. The nonlinear term has a superlinear local ...
Estudo das equações do terceiro grau no ensino médio a partir da equação de Van der Waals
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática em Rede Nacional, 2014-05-30)
Normally, the Basic Education comprises the study of the equations of first and second degree. Most of the textbooks do not address higher order equations. For this reason, we developed a didactic proposal addressing the ...
Equações de segundo grau e mudança de variáveis
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Matemática em Rede NacionalÁlgebra; Análise matemática; Ensino de matemática; Geometria e topologia; Matemática aplicada, 2014-07-11)
In this work are presented, as a review and in a historical context, the most used
methods to solve quadratic equations. It is also shown the simplest type of change
of variables, namely: x = Ay + B where A;B 2 R, and ...
Liouvillian solutions for second order linear diferential equations with polynomial coefcients
(Springer, 2020-09-10)
In this paper we present an algebraic study concerning the general second order
linear diferential equation with polynomial coefcients. By means of Kovacic’s
algorithm and asymptotic iteration method we fnd a degree ...

Métodos históricos utilizados para a resolução de uma equação do segundo grau
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ensino de Ciências Exatas - PPGECE, 2014-09-30)
In this work we attempt to answer the question: Can the methods that great mathematicians have used for almost 4 thousand years of history be helpful in the learning process? With a few years of experience in 2nd degree ...
Análogos del décimo problema de Hilbert = Analogues of hilbert's tenth problem.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Matemática., 2010)
The tenth problem in D. Hilbert's famous list asked the following :
Devise an algorithm to decide whether a polynomial equation
with integer coe cients has an integer solution.
(These equations are called Diophantine ...
Equações do 2° grau em variáveis complexas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Matemática em Rede NacionalUTFPR, 2018-12-07)
In this work a methodology is presented to work on quadratic equations involving complex variables. Firstly, a history of the second-degree equations and complex numbers is presented. Following the formalism involving the ...
