Learning objectives

The knowledge and mastery of the methodological aspects and tools of Differential and Integral Calculus for functions of several real variables required to understand the basic concepts and instruments of the technical-applicational discipline in order to be able to use them to interpret and describe Mechanical Engineering problems.

Teaching methods

The course will take the form of classroom lectures and exercise sessions, which will be an integral part of the course. <br />
<br />
During the course students are given two written progress tests the results of which contribute to the passing of the written exam. Each written test consists of a first part with multiple-choice questions and score threshold, and a second part with open-answer questions. The oral test, which is usually optional, is at the professor’s discretion for students barely passing the written test. <br />
<br />
<br />
Students not wishing to sit the progress tests may sit the written and oral examinations in the exam sessions held subsequent to the end of the course. <br />
