Demonstration of the syllabus coherence with the UC intended learning outcomes

The classes are theoretical and practical.
After exposition, the contents of the lesson is illustrated through application examples and resolution of exercises.
In addition students carry out a work to familiarize themselves with the subjects taught, on the same topics discussed during classes.

Teaching methodologies

Distributed evaluation with a fina exam.
The synchronous classes will be held in the Zoom platform.
The planning of the course, along with all the teaching materials will be made availabre in the Moodle e-learning platform, prior to each class.
