CALCULUS 1 PAR. 1
Learning outcomes of the course unit
Knowledge and understanding.
At the end of the lectures, students should have acquired very good knowledge and understanding of the numerical field N, Q, Z and R, of the numerical sequences and of the differential calculus for functions of one variable.
This course will contribute to makng students able to understand advanced texts in Mathematics and to consult research papers in mathematics.
Applying knowledge and understanding.
By means of the classroom exercises students learn how to apply the theoretical knowledges to solve concrete problems, such as optimization problems.
Students must be able to evaluate coherence and correctness of results obtained by themselves or by others.
Students should be also able to produce precise mathematical arguments clearly identifying the assumptions and the conclusions.
Students must be able to communicate in a clear and precise way mathematical statements in the field of study, also in a context broader than mere calculus. Through the front lectures and the assistance of the teacher, the students acquire the specific and appropriate scientific vocabulary.
This course contributes to making the students able to work in groups and to work with a good degree of autonomy.
The student who has attended the course Analisi Matematica 1, is able to deepen autonomously his/her knowledge of numerical sequences, differential calculus for functions of one variable, starting from the basic and fundamental knowledges provided by the course. He/She will be also able to consult specialized textbook, even outside the topics illustrated during the lectures. This to facilitate the learning of the other activities of the degree course in Mathematics, which use notions from Mathematical Analysis. This course contributes to furnishing a flexible mindset to the student, which helps him/her to easily enter into the labour market, being able to face new problems. Moreover, the course contributes, together with other courses of the bachelor programme, to making the student able to acquire new knowledges in the mathematical fields but also in the labour market field, through an autonomous study. Finally, the course contributes to making the student able to continue the studies in Mathematics or in other scientific disciplines with a high degree of autonomy.

The course schedules 5 hours per week of lectures and classroom exercises. During the lectures the fundamental properties of the numerical sets will be illustrated and basic results of calculus for functions of one variable will be analyzed and discussed. Students will be provided also with the basic results on sequences of real numbers. The classroom exercises aim at showing how and where the abstract results can be applied to make the students understand better the relevance of what they are studying.
The didactic activities of the first half of the course are developped also with the help of a tablet PC which projects on a screen the notes the teacher is writing. A the end of each lesson, a pdf file with the notes of the lecture is uploaded on the elly website. Also a video is uploaded to elly which contains the screen shooting and the audio of the lectures. Lectures and the classroom exercises will be available also online in straming for those students who prefer to attend them at home.
Assessment methods and criteria
The exam of the course Analisi Matematica 1 consists of a written part and an oral part in different dates.
The written part is based on exercises (indicatively 3 or 4) and it is aimed at evaluating the skills of the student in applying the abstract results proposed during the course to some concrete situations. The maximum score of the written part of the exam is 30. The written part is successful if the student reaches a score non inferior to 15.
The oral part is aimed at evaluating 1) the knowledge of the abstract results seen during the course and their proofs 2) the correct use of the mathematical terms, 3) the knowledge of those arguments which have not been included into the written test. The final vote will be given by a
weighted average of the votes of the written and oral part of the exam.
