### Objectives

The course aims to provide the knowledge of abstract concepts and practical methods of differential and integral calculus for functions of one and more variables.

A) Knowledge and understanding
Know the tools of mathematical analysis for the study of functions in one and two real variables and the main methods for the solution of integrals of one real variable functions. Know the concepts of succession and numerical series and the main properties.
B) Ability to apply knowledge and understanding
The student must be able to understand and solve exercises related to the topics of the course and apply the methods studied to simple problems, in order to be able in the future to extend them to other study contexts and / or scientific-technological applications (e.g., Artificial Intelligence).
C) Autonomy of judgment
Being able to identify the most suitable methodologies for solving problems.
D) Communication skills
The student, at the end of the course, should have acquired a minimum basis of mathematical language that allows him to communicate in a scientifically correct way.
E) Learning skills
Based on the knowledge and logical-deductive skills acquired during the course, the student will be able to learn new methods and theories to tackle problems in different application contexts.

Theoretical lessons are supported by numerous exercises with the aim of teaching the student how to approach problem solving.

### Teaching Methods

Teaching will be delivered in person. The lessons can be integrated with audiovisual materials and streaming.
Teacher provides students with course material and exercises to do at home that they will have corrected in the classroom. Didactical methods: interactive lessons with tutorials and individual supervisions. Didactical material at students' disposal: slides and teachers notes, homework exercises and texts available on the platforms recommended by the university. Language utilized: Italian

### Verification of learning

The exam consists of a written and an oral test. Both are rated out of thirty and are considered passed with a rating greater than or equal to 18/30. To access the oral exam it is necessary to pass the written exam. If the oral test is not passed, the student must also repeat the written test. For the determination of the final grade, a weight of 40% will be attributed to the written test and 60% to the oral test.
The write test allows to verify the ability to apply the mathematical contents proposed in class to concrete cases as well as the ability to critically analyze the situations proposed to evaluate the truthfulness of statements concerning specific mathematical situations. It consists of a multiple choice test (5 answer options) in which the student must select the correct options (even more than one for each question). The test is delivered to the PC in one of the university's computer labs and lasts 2 hours. Wrong answers or not given do not give penalties. The student can only use white paper and pen. The result is visible immediately after sending the test and after a few hours the correct answers will also be available and will remain visible at least until the date of the oral tests.
Students will have sample tests available to familiarize themselves with the type of test and the delivery environment.
The oral exam takes place about 5-7 days after the write test and consists of an interview during which the student must demonstrate knowledge of the course contents (definitions of mathematical objects and their properties) and how they are connected, ability to use the process logical-deductive to reproduce known demonstrations, expression and argumentation skills. Three main questions will be proposed but others can be added, aimed at ensuring that the student has mastered the contents (the number of interventions by the teacher depends on the level of preparation of the student and his or her expository skills). Clarifications on the written test may also be requested, especially in case of inconsistencies between the answers given in the written test or between the two tests The duration of the oral test is on average 30 minutes.
The final grade is assigned following the subsequent Docimological Table:
Insufficient: the student demonstrates that he does not know and / or has not understood the fundamental contents of the course.
18-21: The performance of the exercises is affected by significant errors and / or inconsistencies. The oral presentation is unclear; the property of language is limited and knowledge is little more than sufficient.
22-24: the student demonstrates that he has sufficiently understood and assimilated the topics. Oral exposure is affected by hesitations and language properties are limited. Knowledge is adequate.
25-27: the student knows almost all the topics asked in the tests; demonstrates that he has understood and discreetly assimilated the arguments; possesses a good command of language and clarity in exposition.
28-30: the student demonstrates that he has understood and assimilated the topics required for the exam very well; the property of language and clarity of presentation are definitely appropriate.
30 cum laude: the student perfectly knows all the topics asked during the exam; demonstrates that he has understood and assimilated all the topics in depth; has an excellent command of language and exposes the contents very clearly.
The dates of the exams (6 in an academic year) are set for the written test, while the schedule of the oral tests will be communicated after the written test and the analysis of the results (generally this takes place within the day following the written test).
