## Learning Objectives

**First Module****1. Knowledge and understanding:**Assimilation of definitions and main results concerning basic mathematical analysis and functions of one real variable.**2. Applying knowledge and understanding:**acquisition of an appropriate level of autonomy in theoretical knowledge and in the use of basic analytical tools.**3. Making judgements:**ability to draw conclusions, ability to reflect and calculate. Ability to apply the notions learned to solving problems and exercises.**4. Communication skills:**ability to communicate the notions acquired through an adequate scientific language.**5. Learning skills:**ability to deepen and develop the knowledge acquired. Ability to critically use computer tools of symbolic computation.**II**Primary goal of the course is to master the techniques and methods that are peculiar to Mathematical Analysis.

## Course Structure

**First Module**Lectures in classroom. Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programm planned and outlined in the syllabus.

**II**The Teacher via examples and results uses blackboard to show the rigorous methods of Mathematical Analysis.

**Should teaching be carried out blendedly or remotely necessary changes will be set up. Learning assessments may also be carried out on line, should the conditions require it.**
