# ANALISI MATEMATICA 1 PARTE B

Academic Year 2023/2024 - Teacher: Giuseppe DI FAZIO

## Expected Learning Outcomes

Students should be capable of studying qualitative and quantitative properties of single-variable functions and applying them to both theoretical and practical problems. They should be able to graph a function, justifying it based on the theoretical knowledge acquired. Additionally, they should know how to solve relatively simple differential equations. The course provides the necessary skills to effectively tackle the subsequent course in Mathematical Analysis II.

1.General educational objectives of the course in terms of expected learning outcomes:

1. 2.Knowledge and understanding: The course aims to provide a theoretical foundation and some applications related to Differential and Integral Calculus for functions of a real variable.

2. Applying knowledge and understanding: Students will acquire the necessary skills to study simple models.

3. 3.Autonomy in judgment: Through concrete examples and exercises, students will be able to independently develop their own solutions to some simple problems.

4. 4.Communication skills: Students will gain further communication skills and expressive appropriateness in using theoretical language in the context of Mathematical Analysis.

5. 5.Learning skills: The course aims to provide students with the necessary theoretical and practical methodologies to independently address and solve problems that may arise during their design activities.
