Module MODULO B

Teacher: **ANDREA SCAPELLATO**

The aim of the course
of *Mathematical Analysis I - Module B* is to give the basic skills on Integral Calculus for real functions of one
real variable, numerical series and some types of ordinary differential equations.

In particular, the learning objectives of the course, according to the Dublin descriptors, are:

**Knowledge and understanding:**The student will learn some basic concepts of Mathematical Analysis and will develop both computing ability and the capacity of manipulating some common mathematical structures, as integrals for real functions of one real variable, numerical series and some types of ordinary differential equations.**Applying knowledge and understanding:**The student will be able to apply the acquired knowledge in the basic processes of mathematical modeling of classical problems arising from Engineering.**Making judgements:**The student will be stimulated to autonomously deepen his/her knowledge and to carry out exercises on the topics covered by the course. Constructive discussion between students and constant discussion with the teacher will be strongly recommended so that the student will be able to critically monitor his/her own learning process.**Communication skills**: The frequency of the lessons and the reading of the recommended books will help the student to be familiar with the rigor of the mathematical language. Through constant interaction with the teacher, the student will learn to communicate the acquired knowledge with rigor and clarity, both in oral and written form. At the end of the course the student will have learned that mathematical language is useful for communicating clearly in the scientific field.**Learning skills:**The student will be guided in the process of perfecting his/her study method. In particular, through suitable guided exercises, he/she will be able to independently tackle new topics, recognizing the necessary prerequisites to understand them.

During the period of delivery of the lessons, some self-assessment tests will be administered. These self-assessment tests have the task of guiding the student in the gradual learning of the contents displayed during the lessons. In addition, the self-assessment tests allow the teacher to quickly implement any additional activities aimed at supporting students in view of the exams.

The
*Mathematical Analysis I* exam can be passed in three ways.

**Mode
A: mid-term tests and oral tests **

There are two mid-term tests: the first at the end of the first teaching period and the second at the end of the second teaching period. The first mid-term test focuses on the contents of Module A, while the second focuses on the contents of Module B. Each mid-term test consists of a written test and an oral test. The oral exam is compulsory and can only be accessed after passing the written mid-term test. Each mid-term test is considered passed if and only if the interview relating to it has been passed, that is, if the student has obtained a score of at least 18/30. It is possible to take the second mid-term test only if the first has been previously passed. The duration of each written mid-term test is 120 minutes.

*Structure
of the written mid-term tests *

Each
written mid-term test has the same structure. Five exercises will be proposed
in each written mid-term exam.

*Evaluation of the mid-term tests and final
grade*

The maximum grade obtainable in each written mid-term test is 30/30. Each written mid-term test is passed if the student has achieved a score of at least 18/30. A pass is obtained (18/30) if and only if the student correctly solves three of the five proposed exercises. The student who, despite having passed the first mid-term test, has not passed or sustained the second mid-term test, can complete the exam following Mode B, thus supporting the partial written test relating to Module B as well as the oral test after having passed the the written test as a whole. Alternatively, the student can take the complete exam following Mode C. Each oral exam focuses on all the topics of the Module to which it refers. In the formulation of the final mark of each mid-term test, the score obtained in the written mid-term test and the evaluation of the oral test are taken into account. The final grade is the rounding up of the arithmetic average of the marks obtained in the two mid-term tests.

**Mode
B: written test in modules and oral test **

The written test is divided into two partial tests. The first partial test focuses on the contents of Module A, while the second focuses on the contents of Module B. It is possible to take the second partial test only if the first has been previously passed. The duration of each partial test is 120 minutes. It should be noted that, following this procedure, the two partial tests cannot be sustained in the same appeal. After passing the first partial test, the student can take the second partial test in one of the following sessions and in any case no later than the third exam session. The oral exam is compulsory and can only be accessed after passing both partial tests.

*Structure
of partial tests*

The
two partial tests have the same structure. In each partial test five exercises
will be proposed.

*Evaluation of each part into which the written test is
divided*

The maximum grade obtainable in each partial test is 30/30. Each of the two partial tests is considered passed if the student has achieved a score of at least 18/30. In each partial test, passing (18/30) is obtained if and only if the student correctly solves three of the five proposed exercises. The final mark of the written test is the rounding up of the arithmetic average of the marks obtained in the two partial tests.

*Oral
exam and final grade *

The grade with which the student is admitted to the oral test is the rounding up of the arithmetic average of the marks obtained in the two mid-term tests. The oral exam covers all the topics of the course. In formulating the final grade, the grade with which the student is admitted to the oral exam and the grade obtained in the oral exam are taken into account.

**Mode
C: complete written exam and compulsory oral exam **

In this way, only one written test is proposed which focuses on the contents of Module A and on the contents of Module B and, after passing it, the student will have to take the oral test. The written test lasts 120 minutes.

*Structure
of the written test *

Five exercises will be proposed in the written test. Evaluation of the written test. The maximum mark obtainable in the written test is 30/30. The written test is passed if the student has achieved a score of at least 18/30. A pass is obtained (18/30) if and only if the student correctly solves three of the five proposed exercises.

*Oral
exam and final grade *

The
oral exam covers all the topics of the course. In formulating the final grade,
the grade obtained in the written test and the evaluation of the oral test are
taken into account.

All the topics mentioned in the program can be requested during the exam.

The attendance of the lessons, the study of the recommended texts and the
study of the material provided by the teacher (handouts and collections of
exercises carried out and proposed) allow the student to have a clear and
detailed idea of the questions that may be proposed during the exam.

An adequate exposition of the theory involves the use of the rigorous language characteristic of the discipline, the exposition of simple examples and counterexamples that clarify the concepts exposed (definitions, propositions, theorems, corollaries).

The main types of exercises related to the Module B of the course of
*Mathematical Analysis I* are:

- Calculation of indefinite and definite integrals.
- Search the antiderivative of a function satisfying a condition.
- Study of the convergence of improper integrals and calculation of improper integrals.
- Qualitative study of an integral function.
- Study of the behaviour of a numerical series.
- Search the general integral of an ordinary differential equation.
- Search the integral of an ordinary differential equation satisfying a condition.
