Propiedad de las igualdades y despeje de formulas
(2011-07)
Apply properties of equality suggests logical rigor algebraic language use.
An equality is a mathematical expression where two members are linked through the equal sign.
The clearance is a powerful tool not only in ...
Triángulos
(2011)
The triangles are geometric figures which are based on the study of trigonometry. They are important as tools in the previous calculation to describe physical phenomena such as vector analysis of forces, velocities, etc. ...
A geometria do disco de Poincaré
(Universidade Tecnológica Federal do ParanáCuritibaBrasilLicenciatura em MatemáticaUTFPR, 2021-06-21)
In this work, we discuss the history of non-Euclidean geometries, emphasizing a model of hyperbolic geometry in the plane: the Poincaré disk. We relate some results in this geometry to results from Euclidean geometry, such ...
Influence of the tool edge geometry on specific cutting energy at high-speed cutting
(2007-07-01)
This paper presents specific cutting energy measurements as a function of the cutting speed and tool cutting edge geometry. The experimental work was carried out on a vertical CNC machining center with 7,500 rpm spindle ...

An algorithm for automatic checking of exercises in a dynamic geometry system: iGeom
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
One of the key issues in e-learning environments is the possibility of creating and evaluating exercises. However, the lack of tools supporting the authoring and automatic checking of exercises for specifics topics (e.g., ...
Kerr geometry in f(T) gravity
(Springer, 2015-02)
Null tetrads are shown to be a valuable tool in teleparallel theories of modified gravity. We use them to prove that Kerr geometry remains a solution for a wide family of theories of gravity.
Tool geometry optimization in friction stir spot welding of Al-steel joints
(Elsevier, 2017-04)
The necessity to reduce the weight of transport structures, such as cars and airplanes, has become more important due to gas emission regulations. In this regard, the use of hybrid structures made of steel and aluminum is ...
GeoGebra as a Technological Tool in the Process of Teaching and Learning Geometry
(Universidad Nacional de Educación del Ecuador, 2020)
