The student must know trigonometry and mathematical analysis, with particular regard to derivatives and integrals. He must know what a differential is. He must know the basics of analytic geometry, the concept of orthonormal basis, the difference between a scalar and a vectorial quantity, the vector product and the scalar product between vectors. However, these last concepts will be reviewed during the lessons

Attendance is not compulsory even if it is highly recommended in order to fully understand the topics of the programme. During the lessons, a particular effort is made to explain all the mathematical passages necessary for the development of the topic. The lessons are divided into theory (Monday/Wednesday/Friday), exercises (Thursday) and tutoring (the day depends on the availability of the classrooms).

Written and oral exam.

The course is held in person. General information on the course is published on the website of the Department of Basic and Applied Sciences for Engineering (SBAI) on the teacher's page. From year to year the teacher will also activate a GOOGLE CLASSROOM page for the course for which students must register with their Sapienza institutional email address. All communications between teacher and students and the teaching material that will be produced during the lessons will be published on the course page (copy of what is written or projected during the lessons and any video recordings). On the first day of class, all participants will be given and explained the course that will be followed and the program will be delivered.
