Description and Contextualization of the SubjectToggle Navigation
Within the curriculum of the Degree in Business Administration, two mathematics subjects are included: Mathematics I and Mathematics II; both in the first year. The knowledge about univariate calculus acquired in Mathematics I will be basic for the subject Mathematics II, in which the multivariate calculus is studied; these will be fundamental for the analysis and understanding of economic models. The optimization of functions of one and n-variables, with or without constraints, is a very important tool for making decisions in a wide range of economical situations; therefore, we will study some mathematical procedures in order to solve optimization problems. However, we must not forget that the objective of this subject is to provide the students with the quantitative instruments to be able to raise and analyze rigorously economic problems. For that reason, we suggest exercises related to specific economic contexts, from which the students must be able to identify the main components to formulate the corresponding mathematical model to solve it. In addition, we will incorporate the use of the computer to solve problems.
Skills/Learning outcomes of the subjectToggle Navigation
SPECIFIC COMPETENCES
* An ability to manage basic concepts and techniques of multivariate calculus.
* An ability to justify the procedures and the formulation of logical arguments properly using deductive reasoning.
* An ability to formalise quantifiable phenomena related to economic and business science through mathematical models.
TRANSVERSAL COMPETENCES
* Develop learning skills to acquire a high degree of autonomy in order to undertake studies later, as well as to improve their own self-training in a context of continuous changes and innovations.
* Know how to search, identify, analyse and synthesize information from various sources, with critical capacity to assess the situation and foreseeable evolution of a company, make reasoned judgments and take decisions.
* Capacity for written and oral communication.
* Ability to work with responsibility and respect, initiative and leadership.

MethodologyToggle Navigation
Lectures (75%); practical classes (25%).
Practical classes are individual resolution workshops.
- In the event that the health situation, due to the Covid-19, does not allow face-to-face teaching, the teaching would be taught at a distance, using the tools that the University makes available to us.
Assessment systemsToggle Navigation
- Continuous Assessment System
- Final Assessment System
- Tools and qualification percentages:
- Written test to be taken (%): 75
- Team projects (problem solving, project design)) (%): 25
Ordinary Call: Orientations and DisclaimerToggle Navigation
GUIDANCE ON CONTINUOUS EVALUATION
Final written test: up to 7.5 points of the mark.
Individual evaluation of practical classes (problem solving, project design, Individual work): up to 2.5 points of the mark.
WAIVER
Students may waive continuous assessment up to 4 weeks before the end of classes
This waiver must be submitted in writing to the course teaching staff.
The students that waive continuous evaluation will get their total mark by means of the final written test.
In the event that the health situation does not allow the final test to be carried out in person, the procedure specified in the eGela student guide for such situations would be activated.
Extraordinary Call: Orientations and DisclaimerToggle Navigation
The same criteria as in the ordinary evaluation.
However, those students who have been subject to continuous evaluation may waive it and choose to get their total mark by means of a final written test.
Compulsory materialsToggle Navigation
Both in the reprography service of the Faculty of Economics and Business (Gipuzkoa section) and in the virtual platform of the UPV/EHU (eGela), students will have at their disposal the material to be able to follow the lectures, as well as as the collection of exercises proposed for each topic.
