### Learning outcomes of the course unit

Knowledge and understanding: At the end of this course, the student should know the essential definitions and results, and tools of Calculus (limits, differential calculus and integral calculus for real functions of one real variable, ODE ), as well as elements of mathematical Statistic, and he/she should be able to grasp how these enter in the solution of problems.

Applying knowledge and understanding: The student should be able to apply the aforementioned notions to solve mathematical problems not identical but strictly related to those already encountered, as well as to extrapolate the main results to be analyzed from a collection of data.

Making judgements: The student should be able to evaluate coherence and correctness of the solutions given during the written test, by constructing and developing logical arguments with a clear distinction of assumptions and conclusions; the student should be able to check correct proofs and spot wrong reasonings.

Communication skills: The student should be able to communicate in a clear and precise way, via a correct mathematical language, also through group work.

### Recommended readings

One may use any good book on Calculus and Statistics, as e. g.,

M. Abate, "Matematica e Statistica", McGraw Hill.

M. Bramanti, C. D. Pagani, S. Salsa, "Analisi Matematica 1", Ed. Zanichelli.

A. Guerraggio, "Matematica per le scienze", Ed. Pearson.

### Teaching methods

The teaching consists in streaming lessons, via Teams app, where both theoretical and applicable aspects are expounded. The exercises are selected so that the student will be able to solve independently many related problems arising from the theoretical lessons. During the course, the weekly student reception is encouraged for any discussion on mathematical topics and for any individual in-depth analysis.

Further teaching support documents will be shared via the related Elly blog.

### Assessment methods and criteria

Final written test(2h), and possibly in an oral discussion.
