# MATHEMATICAL ANALYSIS 1

## Learning outcomes of the course unit

Knowledge and understanding:

At the end of this course the student should know the essential definitions and results in analysis in one variable, and he 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 forementioned notionsto solve medium level problems, and to understand how they will be used in a more applied context.

Making judgements:

The student should be able to evaluate coherence and correctness of the results obtained by him or presented him.

Communication skills:

The student should be able to communicate in a clear and precise way, also in a context broader than mere calculus.

## Teaching methods

Teaching method:

Oral lessons on line, eventually pre-recorded, practical lessons on line.

Exams:

Written test divided into two parts followed by a colloquium; bi-weekly written exercises during the semester.

## Assessment methods and criteria

Written and oral examination at end.

Knowledge and decoding ability are checked, the first by answering theoretical questions during the oral examination, the second by understanding and decoding the text of complex problems.

The ability to apply knowledge is checked through the solution of proposed problems. The first part of the written test contains both exercises where only basic knowledge has to be applied (if z=5+7i then the suqre of z is...) and exercises requiring understanding of the subject (if z=1+i then the 3257th power of z is...)

The ability to make judgements is checked through the selection of reasonable and unreasonable answers.

Communication skills are checked through an appropriate use of technical language during the oral and written parts.
