Teaching methods and learning activities
The theoretical concepts will be presented during theoretical-practical classes (twice a week, 1.5 h each), where some examples of application will be presented and discussed.
Students will be asked to solve problems outside class time and the professor will be available to clarify students’ doubts.
The laboratory component of this course unit is part of the program of Integrated Laboratories III.
