This paper presents an initiative that seeks to develop some skills of 3-D visualization by using the capabilities of programming and graphical representation of a computer algebra system, in this case Mathematica. A specific procedure has been developed to allow engineering students to represent the families of curves obtained by cutting the 3-D graph of a two-variable function with families of planes...
Truth Tables are a basic tool in the analysis of compound propositions within the field of propositional logic. However, its usefulness extends beyond, covering aspects of Boolean logic, circuit theory, the Algebra of Sets or systems analysis. The symbolic computational system Mathematica has numerous commands for working with propositions, calculate their truth values and get Boolean functions associated...
Universities today offer many courses where the study materials can be obtained online through different mechanisms. The terms e-learning and b-learning are being overshadowed by u-learning (ubiquitous learning), since the learning scenario is any place and any device that can be used to get the materials. The task of preparing the appropriate materials in this new context cannot be addressed individually...
Functions of two variables appear frequently in engineering studies. Students have particular difficulties in understanding how the graphs of these functions are. This paper presents a sequential mode to analyze and reconstruct the graphical information in a function of two variables, up to display its three-dimensional image. This is done by representing the cuts of the graph of the function with...
This paper presents the use of a virtual platform based on Moodle as a supporting element for the acquisition of basic mathematical skills. The project was aimed at first engineering course students whose initial mathematical knowledge presented some shortcomings. After the use of the designed online tools, there has been an increase in pupils' confidence in their mathematical skills and their chances...
