Prerequisites
Standard knoweldge of mathematics provided in high school.
Teaching Methods
Theoretical and exercise lectures. The total amount of theoretical lectures will be about the same as that of exercise lectures.
Further information
The teacher will use Moodle platform as a help for the course, and all students will be invited to register to the Moodle course page. On this page the teacher will upload, along the course, exercises that will be subsequently solved and explained during the lectures.
Type of Assessment
The exam consist of two written parts and a final oral part.
In the first written part the student is asked to solve exercises on the topics of the course: limits and derivatives, study of the graph of a function of one variable, Taylor expansions, infinite series, integrals, local and constrained extrema of functions of several variables. This part can be done also through the intermediate written parts that are set during the course. The sufficiency in this part gives access to the second written part.
The second written part is made of question about theoretical results presented in the course. The student is asked to expose: definitions, statements of theorems and the corresponding proofs.
The oral part is a discussion about the two written parts.
The final grade is an appropriate mean of the grades of the two written parts.
Written and oral exam. The written exam is about two hours long and consists in solving some exercises. In the oral part the written part is analyzed and some questions are posed concerning the theoretical content of the course.
