COMPETENCES AND SKILLS THAT WILL BE ACQUIRED AND LEARNING RESULTS.
This subject provides the quantitative instruments that are needed to pose and analyze economic
problems with the aid of a formal model.
In working towards the above goal the student will acquire the following competences and skills.
Regarding the contents of the course, the student will be able of:

- Study the concept of one variable function and the different properties that a function may
enjoy or not.
- Understand the basic tools of calculus.
- Pose and solve static optimization problems.
- Apply all the above concepts to economic problems.

We classify the competences in two groups: specific competences and generic competences or skills.

Regarding the specific competences, the student will be able to:

- Solve equations, sometimes exactly and sometimes approximately.
- Understand the fundamental concepts involved in the calculus of functions: continuity,
differentiability and integration.
- Describe geometrically the qualitative properties of the functions of one variable, such as
growth, concavity and convexity.
- Approximate a function of one variable using the Taylor polynomial.
- Pose and solve static optimization problems, using the first and second order conditions.
Pertaining the general competences or skills, in the class the student will develop:
- The ability to address economic problems by means of abstract models.
- The ability to solve the above formal models.
- The ability to interpret and classify the different solutions and apply the appropriate conclusions
to social contexts.
- The ability to use the basic tools that are need in the modern analysis of economic problems.
Throughout the course, the student should maintain:
- An inquisitive attitude when developing logical reasoning, being able to tell apart a proof from
an example.
- An entrepreneurial and imaginative attitude towards the cases studied.
- A critical attitude towards the formal results and their applicability in social contexts.

DESCRIPTION OF CONTENTS: PROGRAMME
The course studies theory of functions of one variable. In particular, we focus on the properties of continuity,
derivability, and integration of functions. As soon as the student understands these concepts, they are applied to
the study of problems of interest in Economy, such as monotony and convexity, graphic representation, polynomial
approximation, optimization and calculus of areas.
The program is divided in five big lessons:

Lesson 1: elementary properties of functions. In particular, it is studied when a function is periodic,monotone, shows symmetries or has an inverse.

Lesson 2: continuity. In particular, it is studied when a function has limits and /or asymptotes, the calculus of intersection points of graphics and the existence of maxima and minima.

Lesson 3: differentiability, part one. We study the calculus of derivatives, stressing implicit differentiation. In the same way, we apply derivatives to study monotony and the calculus of maxima and minima.

Lesson 4: differentiability, part two. We use the concept of derivative to compute limits, to approximate locally a function by polynomials, to characterize concavity and convexity of a function and for an introductory study of the income, cost and profit functions.

Lesson 5: Integration. First of all, we introduce the concept of primitive of a function, and we study different methods of computing them. Secondly, we introduce the concepts of area and integral, and its relationship with the concept of primitive function. In a third step, we study the calculus of areas. Finally, we study improper integrals.

LEARNING ACTIVITIES AND METHODOLOGY
The course lectures will be based on combining theoretical explanations with several practical exercises. The students should attempt to solve the exercises by themselves, before they are addressed in class.
Student participation is considered very important in order to acquire the skills needed to pose and solve economic models.

ASSESSMENT SYSTEM
The final grade is the weighted average of the final exam and the class grade. The final exam is the same for all the Mathematics for Economics II groups and consists of practical exercises and theoretical questions. The class grade is determined by each professor and is based on quizzes done in the classes.

Ordinary exam: The final grade is the weighted average of 60% the grade in the final exam and 40% the class grade.

Extraordinary exam: The final grade is the maximum of the following grades:
a) A weighted average consisting of 60% the grade in the final exam and 40% the class grade.
b) The grade in the final exam.
% end-of-term-examination: 60
% of continuous assessment (assigments, laboratory, practicals?): 40

### Course Disclaimer

Please note that there are no beginning level Spanish courses offered in this program.

Courses and course hours of instruction are subject to change.

Eligibility for courses may be subject to a placement exam and/or pre-requisites.

Credits earned vary according to the policies of the students' home institutions. According to ISA policy and possible visa requirements, students must maintain full-time enrollment status, as determined by their home institutions, for the duration of the program.

ECTS (European Credit Transfer and Accumulation System) credits are converted to semester credits/quarter units differently among U.S. universities. Students should confirm the conversion scale used at their home university when determining credit transfer.

Please reference fall and spring course lists as not all courses are taught during both semesters.

Availability of courses is based on enrollment numbers. All students should seek pre-approval for alternate courses in the event of last minute class cancellations

Please note that some courses with locals have recommended prerequisite courses. It is the student's responsibility to consult any recommended prerequisites prior to enrolling in their course.
