Training objectives
- The goal of the course is twofold. On one side the course will give to the students a basic preparation in elementary mathematics, on the other side the course will introduce new mathematical tools based on differential calculus and linear algebra.
Knowledge
Fundamentals of differential calculus , the notion of limit , concept of derivative . Integral as an area. Matrices and linear systems , linear transformations . Simple differential equations and series expansions .
Skill
Ability to qualitatively analyze the behavior of a function and to perform the calculation of some integrals. Solving linear systems .
In addition , students must be able to construct and analyze simple mathematical models ( also connected to differential equations ) with which to formulate problems of Structural Design, Technical Physics and Economy applied to the city and the territory. Prerequisites
- The course requires no prerequisites. In order to standardize the basic preparation of students it is organized an elementary math course called MINIMAT for students who have more gaps in their mathematical education. The verification of this knowledge is carried out through a written test at the beginning of the course.

11. Geometric vectors
Vectors in geometry, free vectors and applied vectors, circular and spherical coordinates, scalar and vector product. Didactic methods
- The course is based on a theorical and a practical part. The practical part through exercises will guide the students in solving problems which are at the basis of the written exam.
Teaching is divided into :
- Basic theoretical knowledge ;
- Practical exercises in the classroom ;
- Verification of learning during the course through individual exercises evaluated by the teacher . Learning assessment procedures
- During the course two written tests or one final written examination. The written test is aimed at verifying the student's ability to solve simple practical problems similar to those seen during exercises in the classroom . The grade of the written test must be integrated with that of the oral exam. The oral examination is based on the verification of theoretical concepts seen during the course and has less impact on the final grade than the written test . There are two types of oral test .
-Type A oral exam (grade larger or equal to 17.5). Two written answers out of six questions proposed. If positive it will confirm the grade obtained in the written part with a maximum increment of 10%. If negative the exam is not sufficient and also the written part must be repeated.
-Type B oral exam (grade larger or equal to 14.5). A single oral exam on the blackboard with two or three questions. If positive it will confirm the grade obtained in the written part with a maximum increment of 30%. If negative the exam is not sufficient and also the written part must be repeated. Reference texts
